如何将2个值表单输入数组放入PHP数组中

Question

I have an input :

  <input type="text" name="input['.$opt_id.']">

and I can get $opt_id value on php side with :

foreach ($_POST['input'] AS $key => $value)
{
    $opt_id=$value;

}

but I want to get second value like this :

 <input type="text" name=input"['.$opt_id.']['.$lang_id.']">

How can I get $opt_id and $lang_id? I want to insert them on different columns in the database.

Answer 1

Assuming that you don't have 2 entries having the same opt_id and lang_id then you can use a single key instead of 2:

HTML:

<input type="text" name="input[<?php echo "{$opt_id}_{$lang_id}"; ?>]" />

PHP:

foreach ($_POST['input'] as $optIdAndLangId => $value) {
    list($opt_id, $lang_id) = explode('_', $optIdAndLangId);
}
