I know how to process something like:
<input type="text" name="Textbox_T[]" id="txBox1" />
but I have an unknown number of boxes (they are generated via javascript and are only known to me after they are submitted) that are named like this:
<input type="text" name="Textbox_T1" id="txBox1" />
Textbox_T1
Textbox_T2
Textbox_T3
Textbox_T4
etc
since I cannot do:
$_GET['Textbox_T'.$i]
how do I do it?
You could set the textbox name to an array:
<input type="text" name="textboxes[]" />
<input type="text" name="textboxes[]" />
<input type="text" name="textboxes[]" />
<input type="text" name="textboxes[]" />
and then in the code
if (is_array($_GET["textboxes"])){
foreach ($_GET["textboxes"] AS $value){
echo $value." entered in a textbox.<br />";
}
}
edit: If you can not change the name, you could iterate over ALL GEt-values:
foreach ($_GET AS $key=>$value){
if (strpos($key, "Textbox") === 0){
echo $value." has been entered in textbox ".$key."<br />";
}
}
Ideally you'd have the javascript add the textareas to submit as an array:
<textarea name="Textbox_T[]" ></textarea>
(I'm assuming you're talking about textareas) because then you just need to loop through that item in PHP once it's been submitted:
foreach($_GET['Textbox_T'] as $text){
//... do something
}
However, if you're stuck with it, you can just loop through your submitted _GET array and attempt to match based on a substring:
$prefix = "Textbox_T";
foreach($_GET as $key=>$value){
if (substr($key,0,strlen($prefix))==$prefix){
//this is one of them! do something
}
}
