how to pass parameter via ajax in php?

Question

PHP

There is such a problem:

<form method="post" action="index.php?action=add&code=<?php echo $row["code"]; ?>">
<input type="text" name="price">
<input type="text" name="name">
</form>

on the side of the php handler, I accept the code (value) parameter, in ajax it turns out like this: data: $(this).serialize(), (I pull data from inputs), I need to get the code value (it is accepted as get) and at the same time pass all the data from the input via ajax

Answer 1

Alternatively, you can simply add 1 hidden input and set the value to $row['code'].
In general, I don’t quite understand why send the form using the standard method if you use ajax.

Answer 2

Hmm, here is POST, here is GET, and AJAX...

<form method=post action="index.php">
<input type=hidden name=action value='add'>
<input type=hidden name=code value='<?php echo $row["code"]; ?>'>
<input type=text name="price">
<input type=text name="name">
</form>

You don’t even need to change anything in AJAX, just do it in index.php instead . if ($_GET['action'] == "add")if ($_POST['action'] == "add")
