How to receive array data from post in php?

Question

I am having a problem to receive array data from select option. Please see code below

Here is my html file

<?php

     $data = array(
             "id" => "1",
             "name" => "John"
     );

?>

<select name="member">
     <option value="`<?php echo $data; ?>`">John</option>
</select>

And here is my php file

$val = $_POST["member"];  
echo $val["id"];

@CORRUPT you put an extra $ at the beginning of your statement. var_dump is a function, not a variable. — ILikeTacos

$val = $_POST['member'] is going to be a string, not an array. So $val['id'] will fail. — ironcito

If you do really want to pass an array from a form, I strongly recommend you to use serialize function.

So in your code.

<select name="member">
    <option value="`<?php echo serialize($data); ?>`">John</option>
</select>

Then in your back-end,

$data = unserialize($_POST["member"]);

Try this. I hope this helps.

Do you mean?

<select name="member">
     <option value="<?php echo $data['id']; ?>">
     <?php echo $data['name']; ?>
     </option>
</select>

Because in your code, you use <?php echo $data; ?> which does not print the value in array, but the string Array which is the type of variable.

Just use the ID and check on the server the other info. Something like this (PHP FIDDLE)(http://phpfiddle.org/main/code/mvr-zde)

Your fiddle won't work on the second submit, best check that.

I intended it for 1 submission. just re-add the data under the if statement if you'd want it to be show again.
