Conditional colors?

[gamadoleo]

Is conditional color supported? tried to add directly via html <font color"red">
however without success, I would like to know what is the recommended way to work with conditional colors, for example I wanted to display a zebra listing with conditioned color.

[Rctnet]

use is_integer($F{rowIndex}/2) into printWhen property on band, create a two bands

[gamadoleo]

I understand is because I don't have this rowIndex in the select, wouldn't it be more interesting to support this conditional no?:
($V{COLUMN_COUNT}% 2) == 0

[Rctnet]

You can add here

JasperPHP/src/Detail.php

Line 30 in c1a338d

$obj->arrayVariable['REPORT_COUNT']["ans"] = $rowIndex;

[gamadoleo]

As you guide requires two bands, I tried something simpler using a rectangle and applying the print condition on it, but it didn't work... are these conditionings also ready for rectangle?

[gamadoleo]

but mind you, jasper report has style functionality and in a style we can add conditional formatting, where can i be testing and modifying to support conditional formatting of the style?

[Rctnet]

I understand now, but i´m sorry, i never use it, where in jasperstudio can be access it ?

[Rctnet]

I found styles, i think what a way to support this
in

JasperPHP/src/Report.php

Line 78 in c1a338d

$this->group_handler($ObjElement);

add a function to read each style and store into a global array, and all objects what you want to use styles, load style property into a object, (all objects are a separate Class) and use styles properties to decore that element, but yet no locate conditional styles, help me about this and i help you to think a way to do this.

[gamadoleo]

thanks for the support, come on I'll demonstrate what I've achieved so far

[gamadoleo]

in Report.php on line 68 I added the following debugging:

            //echo $className."<br/>";               
            if(ucfirst($obj)=='Style'){
            echo "<br/><br/>".$className."<br/>";
            print_r($value);
            echo "<br/><br/>";     
            if(isset($value->conditionalStyle)){
                echo "conditionExpression: ".$value->conditionalStyle->conditionExpression;
                echo "<br/>";                
                //get definition style condicional
                $style= $value->conditionalStyle->style->attributes();
                var_dump($style);   
                echo "<br/>";         
                echo "mode: ".$style['mode']."<br/>";
                echo "backcolor: ".$style['backcolor']."<br/><br/>";   
                
            }
            } 

e o result is:

JasperPHP\Style
SimpleXMLElement Object ( [@attributes] => Array ( [name] => Title [fontName] => Times New Roman [fontSize] => 50 [isBold] => true ) )



JasperPHP\Style
SimpleXMLElement Object ( [@attributes] => Array ( [name] => SubTitle [forecolor] => #736343 [fontName] => Arial [fontSize] => 18 ) )



JasperPHP\Style

conditionExpression:
object(SimpleXMLElement)#9 (0) { }
mode:

JasperPHP\Style

conditionExpression: $V{COLUMN_COUNT}%2 == 0
object(SimpleXMLElement)#8 (1) { ["@attributes"]=> array(2) { ["mode"]=> string(6) "Opaque" ["backcolor"]=> string(7) "#F0F0F0" } }
mode: Opaque
backcolor: #F0F0F0

however, for this to be possible, it is necessary to make an adjustment in the initialization of the xml, I see that I modified it, I would have to see if this affects your structure used so far, but this way it displays the conditional expression of the style:

$xml = simplexml_load_string($xmlFile,null,LIBXML_NOCDATA);

[gamadoleo]

as in the definition of objects, for example, in TextField there is the property style with the name of the style, I believe it is possible to search the definition of the style and apply the conditional

[Rctnet]

i hope what the best way is it

// atribui o conteúdo do label

if(ucfirst($obj)=='Style'){
$this->addStyle($obj); // create a new method into Report.php
}
puclic function addStyle($style){
$this->arrayStyles[] = $style; // here you can trate all parameter of style
}

make this, for example in texfield you get the style property and this line you can get the report object

JasperPHP/src/TextField.php

Line 22 in c1a338d

$obj = is_array($obj) ? $obj[0] : $obj;

you can get $obj->arrayStyles and use it to decorate a element

[gamadoleo]

following your idea I created methods and I can apply exactly the style definitions, all the definitions: background, color and etc... this in TextFiel for now... now I need to see how to apply the conditional style...

in Report.php
add
public $arrayStyles;

add

          //echo $className."<br/>"; 
            // atribui o conteúdo do label
            if(ucfirst($obj)=='Style'){
            $this->addStyle($value); // create a new method into Report.php
            }    

new methods

public function addStyle($style){
//print_r($style);return;
$attributes = $style->attributes();
$key = $attributes['name'];
$this->arrayStyles["{$key}"] = $style; // here you can trate all parameter of style
}

public function getStyle($key){
    if(isset($this->arrayStyles["{$key}"])){
    return $this->arrayStyles["{$key}"];
    }
}
public function applyStyle($key, &$reportElement){
    $style = $this->getStyle($key);
    if($style){
        $attributes = $style->attributes();
        foreach($attributes as $key => $value){
            //ignore
            if(!in_array($key,array('name'))){
                //echo "{$key} - {$value}<br/>";    
                $reportElement[$key]=$value;                             
            }   
        }
    }

in TextField.php

` //print_r( $data["@attributes"]);

    //exist style
    if(isset($data->reportElement['style'])){
    $name = $data->reportElement['style'];
    $obj->applyStyle($name, $data->reportElement);
    }`

[gamadoleo]

that is, now when applying the style, you first need to check the conditional expression to choose which definition to apply the default or the conditional style...

[Rctnet]

this code help you to load and execute expression, i think it is same as printWhenExpression

JasperPHP/src/StaticText.php

Line 127 in c1a338d

$print_expression_result = false;

[gamadoleo]

get it here by modifying a little, so it checks and gets the style according to the conditional, it even accepts more than one conditional in the same style... I just can't say if this will affect the generator's performance... at the same here I haven't seen any effect, but everything can be improved.

[gamadoleo]

modify for

`public function applyStyle($key, &$reportElement, $rowData){
        $style = $this->getStyle($key);
        if($style){
            //default
            $attributes = $style->attributes();
            if(isset($style->conditionalStyle)){ 
                //percore os styles
                foreach($style->conditionalStyle as $styleNew){                
                    $expression = $styleNew->conditionExpression;             
                    //echo $expression;
                    $resultExpression = false;
                    $expression = $this->get_expression($expression, $rowData);
                    //echo 'if(' . $expression . '){$resultExpression=true;}<br/>';
                    eval('if(' . $expression . '){$resultExpression=true;}'); 
                    //echo $resultExpression."<br/>";
                    if($resultExpression){
                        //get definition style condicional
                        $attributCondicional= $styleNew->style->attributes();
                        $attributes = $attributCondicional;
                        break;
                        //var_dump($attributCondicional);  
                    }      
                }
            }           
           //change propriedades 
            foreach($attributes as $key => $value){
                //ignore
                if(!in_array($key,array('name'))){
                    //echo "{$key} - {$value}<br/>";    
                    $reportElement[$key]=$value;                             
                }   
            }
           
        }        
    }`

great!!

about adding new variables I added in
Report.php
$obj->arrayVariable['COLUMN_COUNT'] = $rowIndex;//by gamadoleo

however to work the replace I had to make a small adjustment in the getValOfVariable method in the last one else

//by gamadoleo
if($ans==''){
return str_ireplace(array('$V{' . $variable . '}'), $val, $text);
}
return str_ireplace(array('$V{' . $variable . '}'), array($ans), $text);

[gamadoleo]

the way I did the application of the style, it performs the conditional check on each TextField object, I don't know if I would be able to reduce this check, you who are more inside can analyze my function and see if you can improve the performance. but in the test here a 71 page report generates in less than 10s, but as I said everything can be improved.

[Rctnet]

ok, send a Pull Request with yours updates

[Rctnet]

add zebra style to cities sample

[gamadoleo]

OK, just confirm about adding new variables for replication if I did something wrong? to not need to modify a getValOfVariable function

no details I added like this:
$obj->arrayVariable['COLUMN_COUNT'] = $rowIndex; // by gamma oil

however, tweak the getValOfVariable function

[gamadoleo]

I will provide the example and send

ignore the aforementioned setting of Variable, actually the REPORT_COUNT works for me
