Question

Hi Stackoverflow i hope you are all well today,

i seem to have run into an issue and am kindly requesting your assistance;

Basically i am using jQuery to manipulate a form, the form then stores in the session and upon returning to the page a foreach loop is used to return the values from the session into the page.

The issue is if I create more than one instance of this foreach loop it gives me an invalid argument (if i add the same code over and over again it works fine)

So firstly here is the code;

jQuery

    $(function(){
$('.add_child').click(function(){
    var attrName = $(this).attr('name');
    var count = $(this).attr('count');
    $(this).attr('count', (parseInt(count)+1))
    var input = $('<input />');
    var lineBreak = $('<br/>');
    input.attr('type','text')
    input.attr('name',attrName+"["+count+"]" ) 
    $('.children_form').append(input);
    $('.children_form').append(lineBreak);
})
$('.add_s_child').click(function(){
    var attrName = $(this).attr('name');
    var count = $(this).attr('count');
    $(this).attr('count', (parseInt(count)+1))
    var input = $('<input />');
    var lineBreak = $('<br/>');
    input.attr('type','text')
    input.attr('name',attrName+"["+count+"]" ) 
    $('.spouce_children').append(input);
    $('.spouce_children').append(lineBreak);
})
});

and the PHP / HTML CODE -> Button One (add_child)

Children, please name your natural and / or addopted children

<?php foreach($_SESSION['children'] as $index=>$child){ ?>
<?php echo "<input type='text' name='children[{$index}]' value='{$child}'/>";?>
<?php } ?>

<input type="button" count='<?php echo count($_SESSION['children']);?>' name="children" class="add_child" value="Add Another Child"/>

<div class="children_form">
<?php //add the inputs here?>   
</div>

and the PHP / HTML CODE -> Button Two (spouce_children)

<label>Spouces Children, please name all natural and addopted children</label>
<input type="text" name="spoucechild" id="spoucechild" />

<?php foreach($_SESSION['spoucechild'] as $index=>$child){ ?>
<?php echo "<input type='text' name='spoucechild[{$index}]' value='{$child}'/>";?>
<?php } ?>

<input type="button" count='<?php echo count($_SESSION['spoucechild']);?>' name="spoucechild" class="add_s_child" value="Add Another Child"/>
<div class="spouce_children">
    <?php //add the inputs here?>     
</div>

I would like to thank you for any help you can / will provide <3

Error Occurs here:

<?php foreach($_SESSION['spoucechild'] as $index=>$child){ ?>

@Xavier: You could try —

<?php
if (isset($_SESSION['spoucechild'])) {
    foreach($_SESSION['spoucechild'] as $index=>$child){
        echo '<input type="text" name="spoucechild[' . $index . ']" value="' . $child . '" />' . "\n";
    }
}
?>
