Modules and Undefined index alerts

Hi, I have created a custom module and I’m facing a insolvable (form me) problem:

I have serveral checkboxs named (delimg1, delimg2, etc..) and in the result part of my script I’m using $_POST["delimg$i"] to check if the variables was sent and in the case I’m using the value.

I’m using something la this :

                    for ($i=1;$i<=$_POST['totalImg'];$i++){
                                if (isset($_POST["delimg$i"]) ){
                                   ....
                                }

                    }

The module is working, BUT when I select less all the chekboxs I have a MODx "Undefined index:delimgNOTSELECTED" alert and I really dont know how to correct my module script.

I initialize all my variables but here I don’t know how to do it because I don’t know how many checkboxs I will have.

It’s the only thing I have to do before my client can use the all site, so I really need help ! Thanks A LOT

Hi laurent,

I’ve faced the same issue with tvEditor

To fix it I’ve used strpos to find the prefix name of the variable in the posted value.
hope that helps

:-)

here is the function


<?php

	function handleValue($external,$allowed=array()){
	
	$posted= array();
	
	if(!is_array($external)) return false;
	
		foreach($external as $key => $value){
			
			if(in_array($key,$allowed) || (strpos($key,implode("," ,$allowed))!==false)){
				
				if(is_array($value) && (strpos($key,"option") !== FALSE) ){
				
					$posted['options'] = $this->handleOptionsValues($posted['options'],$key,$value);
				
				}else{
				
					$posted[$key] =  $value ;
					
				}
			
			}elseif(is_array($string = explode("_",$key)) && in_array($string[0],$allowed)){
			
				$posted[$string[0]][] = $value ;
			}
		}
	
	return $posted;
	
	}

$tveditor->posted = $tveditor->functions->handleValue($_REQUEST,$tveditor->allowed);
