Why I do not get radio button value with php? - php

Question

I´m passing a value of a radio button in a page with a form and I want to get the value of the selected option in another php file, but I can´t get that value.
First page:
<form class="itemSelection" action="../php/itemSelection1Save.php"><br><br>
<h1>Recommended Item(s)</h1>
<table class="itemTableRecom">
<thead>
<tr>
<th>Selected Item Type</th>
<th>Recommended Item Type</th>
</tr>
</thead>
<tbody>
<?php
foreach ($_SESSION['itemsInfo'] as $row) {
?>
<tr>
<td><input type="radio" name="selectedItem" id="selectedItem" required="" value="<?php echo $row[0] ?>"></td>
<td><?php
echo row[0]</td>
</tr>
<?php
}
?>
</tbody>
</table><br>
<input type="submit" value="Next"/>
</form>
Second file:
$_SESSION['selectedItem1'] = filter_input(INPUT_POST, 'selectedItem');
filter_input(INPUT_POST, 'selectedItem')
returns nothing

Answer 1

You form is with method get (the default method if not specified):
<form class="itemSelection" action="../php/itemSelection1Save.php">
insert method='post':
<form class="itemSelection" action="../php/itemSelection1Save.php" method='post'>

Answer 2

Make the following changes in HTML part , add method="post"
<form class="itemSelection" action="../php/itemSelection1Save.php" method="post">
Make the following change in PHP part (optional):
Also add filter_option in filter_input. filter the ID or name of the filter to use. Default is FILTER_DEFAULT, which results in no filtering.
filter_input(INPUT_POST, 'selectedItem',filter_option)
