How can I post an id using a link like <a href="#"></a> instead using a select like <select> <option value="">Elegir cliente</option></select>?

I'm trying to get a id using method post with <a href="#"></a> While loading plugin but I don't get it. For example if I use el select like this

<select name="customerID" required="required" class="form-control-file" id="customerID" title="Elija un cliente" onChange="WADFP_Show_Progress('Checkout_form_ProgressMessageWrapper', WADFP_Theme_Options['BigSpin:Pacifica']);framework_load_plugin_url('plugins/checkout/addresses.php',document.getElementById('Checkout_form'),'customers','../','');return document.MM_returnValue">
<option value="">Elegir cliente</option>
<?php
while(!$Customer_RS->atEnd()) { //dyn select
?>
<option value="<?php echo($Customer_RS->getColumnVal("customer_id")); ?>"><?php echo($Customer_RS->getColumnVal("firstname")); ?>&nbsp;<?php echo($Customer_RS->getColumnVal("lastname")); ?></option>
<?php
$Customer_RS->moveNext();
} //dyn select
$Customer_RS->moveFirst();
?>
</select>



I get it working proper but I need to design it like this for better look


BUT THIS METHOD DOESN'T WORK. IT LOOK LIKE NO POST PASSING
<?php
$wa_startindex = 0;
while(!$Profile_RS->atEnd()) {
$wa_startindex = $Profile_RS->Index;
?>
<div class="col-lg-6">
<div class="feature-item">
<h3><a href="#" name="md" class="text-decoration-none" onClick="framework_load_plugin_url('plugins/plugins/details.php',document.getElementById('Checkout_form'),'callme','../','');return document.MM_returnValue"><?php echo($Profile_RS->getColumnVal("firstname")); ?> <?php echo($Profile_RS->getColumnVal("lastname")); ?></a></h3>
<input type="hidden" name="md" id="md" value="<?php echo($Profile_RS->getColumnVal("bg_id")); ?>">
</div>
</div>
<?php
$Profile_RS->moveNext();
}
$Profile_RS->moveFirst(); //return RS to first record
unset($wa_startindex);
unset($wa_repeatcount);
?>

You can't have both an onClick function and valid href attribute in <a>. Change your anchor element to:

<a href="javascript:void(0)" name="md" class="text-decoration-none" onClick="framework_load_plugin_url('...

I only want to have one but when I use the one with the link I only have one ID From the recordset despite I have the value inside the loop. I it should have one value for each link

You probably need a hidden input outside of the loop. Then set the value of the hidden field using javascript. Something like:

<?php

$wa_startindex = 0;

while(!$Profile_RS->atEnd()) {

$wa_startindex = $Profile_RS->Index;

?>

<div class="col-lg-6">

<div class="feature-item">

<h3><a href="#" name="md" class="text-decoration-none" onClick="document.getElementById('md').value='<?php echo($Profile_RS->getColumnVal("bg_id")); ?>';document.getElementById('customerID').value='<?php echo($Profile_RS->getColumnVal("customer_id")); ?>';framework_load_plugin_url('plugins/plugins/details.php',document.getElementById('Checkout_form'),'callme','../','');return document.MM_returnValue"><?php echo($Profile_RS->getColumnVal("firstname")); ?> <?php echo($Profile_RS->getColumnVal("lastname")); ?></a></h3>

</div>

</div>

<?php

$Profile_RS->moveNext();

}

$Profile_RS->moveFirst(); //return RS to first record

unset($wa_startindex);

unset($wa_repeatcount);

?>

<input type="hidden" name="md" id="md" value="">

<input type="hidden" name="customerID" id="customerID" value="">

Thank you so much that works properly!
