Question

Might seem like a stupid question, but I’m having an issue creating an array from multiple POST variables. They are coming from a jQuery form that can have any number of variables. It can be 1 of 2 options, name or school.

For example: $_POST['name1'], $_POST['school2'], $_POST['name3'], $_POST['name4'], etc.

Is there a way to get the max number of variables and put each variable into an array? Or is there a better way of doing this?

Any input is appreciated.

Answer 1

<input name="name[]" />
<input name="school[]" />
<input name="name[]" />
<input name="name[]" />

Is that what you mean? PHP Form Arrays Then, reference wise, you now have an array for $_POST['name'] and $_POST['school']

foreach ($_POST['name'] as $name)
{
  // each form element from the `name[]` inputs = $name
}
foreach ($_POST['school'] as $school)
{
  // each form element from the `school[]` inputs = $name
}

Alternatively, if you’re numbering them you can use a foreach on the $_POST variable:

foreach ($_POST as $key => $val)
{
  if (preg_match('/^name\d+$/',$key){
    // name variable
  } else if (preg_match('/^school\d+$/',$key){
    // school variable
  }
}
