PHP $_POST with variable name

Question

I have dropdown fields on an event website with variable names so I'm unsure on how to capture the data with $_POST

An example is

tkt-slctr-qty-346[]
tkt-slctr-qty-358[]

Is there a way to capture the data with $_POST by using wildcards at all?

EDIT: here is the html

    <select name="tkt-slctr-qty-346[]" id="ticket-selector-tbl-qty-slct-346-1" class="ticket-selector-tbl-qty-slct">
   <option value="0">&nbsp;0&nbsp;</option>
   <option value="1">&nbsp;1&nbsp;</option>
   <option value="2">&nbsp;2&nbsp;</option>
   <option value="3">&nbsp;3&nbsp;</option>
   <option value="4">&nbsp;4&nbsp;</option>
   <option value="5">&nbsp;5&nbsp;</option>
   <option value="6">&nbsp;6&nbsp;</option>
   <option value="7">&nbsp;7&nbsp;</option>
   <option value="8">&nbsp;8&nbsp;</option>
   <option value="9">&nbsp;9&nbsp;</option>
   <option value="10">&nbsp;10&nbsp;</option>
</select>

Answer 1

Instead of having the id as part of the "name" (which will be used as the key in the $_POST array, PHP supports using array notation directly:

name="tkt-slctr-qty[346]"
name="tkt-slctr-qty[358]"

You can then iterate over these under a single key:

if (!empty($_POST['tkt-slctr-qty']) && is_array($_POST['tkt-slctr-qty'])) {
    foreach ($_POST['tkt-slctr-qty'] as $id => $qty) {
        // handle each id/qty value
    }
}

If you do have multiple select boxes for each id as well, append [] to each, and create an inner loop:

name="tkt-slctr-qty[346][]"

...

name="tkt-slctr-qty[358][]"

And then handle it in an inner loop:

if (!empty($_POST['tkt-slctr-qty']) && is_array($_POST['tkt-slctr-qty'])) {
    foreach ($_POST['tkt-slctr-qty'] as $id => $qtys) {
        if (is_array($qtys)) {
            foreach ($qtys as $qty) {
                // handle each qty if there are multiple fields.
            }
        }
    }
}

You can get post variables to an array then iterate through it while you filter.

foreach($_POST as $key => $value) {
  $pos = strpos($key , "tkt-slctr-qty-");
  if ($pos === 0){
    // do something with $value
  }
}

When you submit those arrays, PHP will receive them this way:

$_POST['tkt-slctr-qty-358'][0]
$_POST['tkt-slctr-qty-358'][1]
// ...

If you mean to capture the numbers at the end of the key dynamically, it works the following:

foreach ($_POST as $k => $v) {
    if (strpos($k, 'tkt-slctr-qty-') === 0) {
        foreach ($v as $innerValue) {
            echo 'Key: ' . $k . ' has value: ' . $innerValue . '<br>';
        }
    }
}

You have to Iterate through the $_POST array holding the collection. Follow the pattern below

$counter = count($_POST['tkt-slctr-qty-346']);
    $image = '';
        for($i=0; $i< $counter; $i++)
        {
        $data = $_POST['tkt-slctr-qty-346'][$i];
        //Then Write the code that processes the data here
        }
