50 موضوعاً لمساعدة أصحاب متاجر Shopify — مع أمثلة أكواد مجانية وتحذيرات واضحة

سننشر سلسلة تشرح مشاكل Shopify بلغة يفهمها صاحب المتجر: ما سبب المشكلة، ومتى يفيد الكود، وأين يوضع، وكيف تختبره وتتراجع عنه.

تنبيه مهم: الأكواد المقترحة أمثلة عامة وليست إصلاحاً مضموناً لكل متجر. انسخ القالب احتياطياً، وجرّب على نسخة غير منشورة، ولا تعدّل المتجر المباشر قبل التأكد من التوافق. إذا لم تفهم وظيفة الكود أو مكانه، اطلب المساعدة أولاً.

Your Shopify problem deserves a clear answer—not another unexplained code block

We are building a 50-topic free Shopify code series for owners who want to understand and improve their stores.

This page is the publication roadmap. The rows below describe planned guides and code suggestions, not 50 completed or tested fixes. The first FAQ starter example is already available in our help discussion.

These are editorial topics based on practical troubleshooting areas—not a claimed search-volume ranking or a list of verified customer incidents.

Read this before using any code

General code suggestion—not a universal fix. Your theme version, installed apps, market settings and existing customizations can change how code behaves. Duplicate and back up your theme first. Work on the unpublished copy. Read the placement and compatibility notes, change one thing at a time, and test before publishing. Keep the original code so you can undo the change. If you cannot explain what the code changes, ask for guidance before installing it.

A theme copy does not back up product records, app settings or every store configuration. Any guide affecting those areas must explain the separate backup and recovery steps.

Be especially cautious with product forms, variants, cart requests, prices, tracking, canonical tags and structured data. Where a setting or app configuration is the proper solution, we will explain it instead of adding unnecessary code.

What each published guide will include

1. The exact owner question and why the problem matters to shoppers.
2. Checks to confirm the cause before editing anything.
3. A free, focused code suggestion—or a no-code fix when appropriate.
4. Exact file/field placement: add, replace or adapt; never simply “paste in theme.liquid.”
5. Theme/version assumptions, dependencies and situations where it should not be used.
6. A clear caution beside the code, including its specific failure risks.
7. Desktop, mobile and relevant accessibility or purchase-flow checks.
8. Rollback instructions and an honest verification status.
9. Relevant official documentation and the date reviewed.
10. Links to the discussion, LinkedIn group and free Shopify consultation.

Verification labels: “illustrative example,” “syntax checked,” or “tested on [named theme/version]” will mean different things. Syntax checks alone do not prove a fix works on your store.

1. Theme sections and Liquid

#	Owner question	Planned free code suggestion	Specific caution
1	Why is my new Shopify section missing from Add section?	A minimal section schema and preset example.	A section file and a theme block are different; do not paste one into the other.
2	Why does editing one product page change all products?	A product-specific display condition, alongside separate-template instructions.	Check every product assigned to the template; code may not be necessary.
3	How do I show a custom section only on product pages?	A request/page-type condition for a specific custom component.	Do not wrap the entire layout or essential theme output.
4	Why does Shopify show a Liquid syntax error?	A corrected conditional example with balanced Liquid tags.	Fix the exact reported error; replacing an entire file can remove unrelated features.
5	Why is my snippet not receiving the value I pass to it?	An explicit render parameter and matching snippet example.	Render has its own scope; match variable names and avoid passing private data.
6	Why does my section display empty headings or blank boxes?	Blank-value guards around optional content.	Do not hide the whole product form because one optional setting is empty.
7	How do I stop my custom CSS changing other sections?	A section-scoped selector pattern.	Keep selectors aligned with the component; broad overrides can break the rest of the store.
8	Why does Shopify reject my section settings?	A minimal valid schema with correctly matched setting IDs.	Schema belongs in the correct theme file, not in a Custom Liquid editor field.
9	Why do copied sections open the wrong accordion or tab?	Unique component IDs and matching control references.	Check duplicate instances and keyboard operation, not just one section.
10	Why are my custom changes missing after a theme update?	A documented custom asset and include pattern.	Keep a backup and change record; no snippet makes all customizations update-proof.

2. AI-generated sections and JavaScript

#	Owner question	Planned free code suggestion	Specific caution
11	My AI-generated section looks finished—how do I make it actually appear?	Separate examples for section registration and appropriate rendering.	First identify whether the generator created a section, block or snippet; there is no universal activation line.
12	Why does my AI section work live but fail in the theme editor?	An initialization pattern for initial load and section reload events.	Clean up listeners and timers; do not initialize the whole page repeatedly.
13	Why does one click trigger my Shopify button twice?	Idempotent event binding for a custom component.	Avoid removing listeners belonging to the theme or an app.
14	Why does my custom script run before its element exists?	DOM-ready initialization with a missing-element guard.	Do not hide unrelated errors or delay all theme scripts.
15	Why does my custom section stop working when I add it twice?	Per-instance element lookup inside the component root.	Avoid global IDs and selectors that always pick the first instance.
16	How do I keep essential AI-generated text in the page HTML?	A Liquid/HTML content example with JavaScript used only for enhancement.	HTML availability does not guarantee search indexing or AI recommendations.
17	Why does my custom JavaScript file show a 404 error?	A theme asset URL include with the correct filename.	Upload the asset first and respect case; do not replace all existing includes.
18	How do I load a custom script only where it is needed?	A conditional include for one nonessential component.	Do not conditionally remove scripts required by navigation, product forms or cart.
19	How do I transfer a Liquid value into JavaScript safely?	A serialization example suited to its HTML/script context.	Quotes and closing-script characters need context-aware handling; never expose secrets.
20	How do I show a helpful message when a custom request fails?	A response-status check and accessible error state.	Do not retry cart or other write requests blindly; duplicate operations can affect orders.

3. Mobile, accessibility and Arabic layout

#	Owner question	Planned free code suggestion	Specific caution
21	Why can shoppers scroll sideways on my mobile store?	A scoped width/min-width correction after locating the overflowing element.	Do not apply global overflow hiding to conceal the cause.
22	Why are my product images stretched?	A responsive image ratio and sizing example.	Choose contain or cover intentionally; cover may crop product details.
23	Why does my custom product grid break on small screens?	A responsive CSS grid scoped to the custom section.	Check long product names, price text and the narrowest supported screen.
24	Why is my mobile menu button difficult to tap?	A scoped tap-target and spacing adjustment.	Preserve button semantics and check overlapping elements.
25	Why can keyboard shoppers not see where they are?	A focus-visible outline for custom controls.	Do not remove existing focus indicators or create a keyboard trap.
26	Why does my sticky header cover anchor-linked content?	A scroll-margin adjustment on the destination section.	Use the real header height and verify different screen sizes.
27	How can I respect shoppers who prefer less animation?	A reduced-motion rule for nonessential custom animations.	Do not disable transitions essential to understanding or operating a component.
28	Why does my Arabic storefront layout feel reversed incorrectly?	Logical CSS properties for a scoped component.	Test mixed Arabic, English, numbers and icons; avoid reversing every flex container.
29	Why do long names or URLs break my product cards?	Scoped wrapping and flexible-width CSS.	Check SKU codes and prices remain readable; do not truncate critical information.
30	How do I add an accessible FAQ without another app?	A native details/summary HTML example.	Use accurate merchant answers, test the keyboard, and avoid duplicate structured data.

4. Product pages, cart and forms

#	Owner question	Planned free code suggestion	Specific caution
31	Why does my custom price show the wrong currency format?	Shopify money-filter output instead of manually appended currency text.	Respect the active market and existing price component; formatting does not change checkout currency.
32	Why does my sale badge appear when there is no real discount?	A compare-at-price condition for the relevant variant.	Variant changes must update the badge; do not manufacture a discount.
33	Why does my custom Add to cart button add the wrong variant?	A variant-ID submission example with a visible selector.	Check sold-out variants and app integrations; this is not a universal product-form replacement.
34	Why does my custom quantity field accept invalid quantities?	A quantity-input example respecting relevant limits and increments.	Client-side limits are not authoritative; cart responses and quantity rules still matter.
35	Why is my product image blank when no featured image exists?	A Liquid image-presence guard with an intentional fallback.	Do not substitute an unrelated product image or hide a purchasing control.
36	How do I add useful image alt text without keyword stuffing?	An escaped alt-text output and fallback pattern.	Describe the image truthfully; decorative images may need empty alt text.
37	Why does my custom contact form submit without useful feedback?	A Shopify contact-form example with success and error output.	Do not nest forms; use correct field names and test actual delivery separately.
38	Why does the cart count stay unchanged after adding an item?	A count-refresh example based on confirmed cart state.	Integrate with the theme's own cart events; do not add an extra cart mutation.
39	Why does a failed Add to cart request look successful?	An error-response branch and visible status message.	Only show success after confirmation; preserve stock and validation error messages.
40	Why do links in my custom section lose the shopper's language path?	Locale-aware route output for supported storefront destinations.	Do not hardcode every link to the root language or assume all URLs use the same prefix.

5. Performance, search visibility and structured content

#	Owner question	Planned free code suggestion	Specific caution
41	Why is my main banner slow to appear?	A responsive image example with deliberate loading priority.	Identify the real largest-content image first; do not preload every image.
42	Why does the page jump as images load?	Image dimensions and aspect-ratio reservation.	Keep dimensions proportional to the actual image; do not force distortion.
43	How do I lazy-load lower-page images without slowing the hero?	An image-loading example for genuinely below-the-fold content.	Do not lazy-load the initial main banner by default.
44	Why does a custom video slow down the product page?	A poster and deliberate preload/playback pattern.	Keep controls usable and do not assume autoplay works on mobile.
45	How do I reduce unnecessary custom font downloads?	A limited font-face strategy with an appropriate fallback.	Use properly licensed assets and test layout shifts before changing brand typography.
46	Why does my page contain duplicate canonical tags?	A single canonical-output pattern after identifying existing output.	Do not paste a second tag or change canonical targets without checking the affected URLs.
47	Why are custom product titles or descriptions rendering broken HTML?	Escaped plain-text metadata output.	Preserve existing SEO logic; escaping and rich HTML rendering serve different contexts.
48	How do I avoid duplicate or inaccurate product structured data?	A conditional product-data example after auditing theme and app output.	Never invent ratings, availability or prices; validate the final rendered page.
49	Why are products missing from my custom collection grid?	A paginated collection-loop example.	Do not replace a working grid blindly; preserve filters, sorting and pagination links.
50	How do I make a custom help section useful for search and AI answers?	Semantic headings, visible answer text and descriptive internal links.	Answer real buyer questions; neither markup nor a file can guarantee rankings or AI inclusion.
