初始化javascript变量以重复表单中的部分

Question

I have a form with a repeating section that uses jQuery to clone the section and increment the ids. Now I need to initialize the variables in order to send the form via PHP.

HTML:

<div class="repeatingSection">
<label for="poste_1">Poste :</label>
<input type="text" name="poste_1" id="poste_1"/>
<label for="date_1">Date :</label>
<input type="text" name="date_1" id="date_1"/>
</div>

JQUERY:

jQuery('.cloneButton').click(function(event){

event.preventDefault();

var currentCount =  jQuery('.repeatingSection').length;
var newCount = currentCount+1;
var lastRepeatingGroup = jQuery('.repeatingSection').last();
var newSection = lastRepeatingGroup.clone(false).find('.cloneButton').remove().end();

newSection.insertAfter(lastRepeatingGroup);
newSection.find("input").each(function (index, input) {
    input.id = input.id.replace("_" + currentCount, "_" + newCount);
    input.name = input.name.replace("_" + currentCount, "_" + newCount);
});
newSection.find("label").each(function (index, label) {
    var l = jQuery(label);
    l.attr('for', l.attr('for').replace("_" + currentCount, "_" + newCount));
});
return false;
});

jQuery(document.body).on('click','.removeButton', function(){

    jQuery(this).closest('div.repeatingSection').remove();
    return false;
});

PHP :

$poste1 = '';
$date1 = '';
$poste1 = trim($_POST['poste_1']);
$date1 = trim($_POST['date_1']);

I know I would need to put them in an array and loop through them but I'm not sure how to go about it.

You can use a for loop and a count variable from javascript and do something like :

for($i=1; $i<$currentCount; $i++) { 
${"poste".$i} = trim($_POST["poste_$i"]);
${"date".$i} = trim($_POST["date_$i"]);
}

You would have variables $poste1 and $date1. Using ${''} creates dynamic variables.
