Get values of radio selected values of entire row to next file - php

Question

I have displayed the values from mysql table along with radio buttons with different values. On submit button it should redirect to next page and display the selected values. My code on first file is as follows :
$query1 = "select * from booking";
$result1 = $connection->query($query1);
echo "<form method='post' action='edit.php'>";
echo "<center>";
echo "<table border='1'>";
$count = 0;
while($row = $result1->fetch_row())
{
echo "<tr>";
echo "<td width=".'10'.">";
$count = $count + 1;
#$sr=$sr+1;
echo "<input type='radio' name='select' value='".$count."' />";
#$row = mysqli_fetch_row($result1);
#echo "<tr>";
echo "<td width=".'10'.">";
$rooms = $row[0];
$srrooms = $rooms;
echo "<input type='text' name='srrooms' value='".$srrooms."' hidden='hidden'>";
#echo $srrooms;
echo $rooms;
echo "</td>";
echo "<td width=".'10'.">";
$no_roomss = $row[1];
$nosrrooms = $no_roomss;
echo "<input type='text' name='nosrrooms' value='".$nosrrooms."' hidden='hidden'>";
echo $no_roomss;
echo "</td>";
echo "<td width=".'10'.">";
$no_dayss = $row[2];
$nodays = $no_dayss;
echo "<input type='text' name='nodays' value='".$nodays."' hidden='hidden'>";
echo $no_dayss;
echo "</td>";
echo "<td width=".'10'.">";
$name = $row[3];
echo $name;
echo "</td>";
echo "</tr>";
#$count++;
}
echo "<input name='count' type='hidden' id='count'>"; // hidden input where counter value will be stored
echo "</table>";
echo "<input type='submit' name='submitRooms' />";
echo "</center>";
echo "</form>";
The javascript code is :
$(function(){
$('input[name="select"]').change(function(){
$('#count').val($("input[name='select']:checked").val());
});
});
edit.php code is :
<?php
if(isset($_POST['submitRooms'])){
#$count = $_POST['count'];
#$srrooms=$_POST['srrooms'.$count];
#$nosrrooms=$_POST['nosrrooms'.$count];
#$nodays=$_POST['nodays'.$count];
echo 'Selected values are: '. $srrooms . $nosrrooms . $nodays;
}
?>

You can use counter for submitting the values of the selected radiobutton's row as:
<?php
$query1 = "select * from booking";
$result1 = $connection->query($query1);
echo "<form method='post' action='edit.php'>";
echo "<center>";
echo "<table border='1'>";
$count = 0; // counter variable
while($row = $result1->fetch_row())
{
echo "<tr>";
echo "<td width=".'10'.">";
echo "<input type='radio' name='select' value='".$count."' />";
echo "<td width=".'10'.">";
$rooms = $row[0];
$srrooms = $rooms;
echo "<input type='hidden' name='srrooms".$count."' value='".$srrooms."' >"; // add counter value to every name of the input fields
echo $rooms;
echo "</td>";
echo "<td width=".'10'.">";
$no_roomss = $row[1];
$nosrrooms = $no_roomss;
echo "<input type='hidden' name='nosrrooms".$count."' value='".$nosrrooms."'>";
echo $no_roomss;
echo "</td>";
echo "<td width=".'10'.">";
$no_dayss = $row[2];
$nodays = $no_dayss;
echo "<input type='hidden' name='nodays".$count."' value='".$nodays."' >";
echo $no_dayss;
echo "</td>";
echo "<td width=".'10'.">";
$name = $row[3];
echo $name;
echo "</td>";
echo "</tr>";
$count++;
}
echo "<input name='count' type='hidden' id='count'>"; // hidden input where counter value will be stored
echo "</table>";
echo "<input type='submit' name='submitRooms' />";
echo "</center>";
echo "</form>";
?>
and then use jquery for saving the active radiobuttons count in the hidden count input field [after the above php code]
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>
<script type='text/javascript'>
$(function(){
$('input[name="select"]').change(function(){
$('#count').val($("input[name='select']:checked").val());
});
});
</script>
then on your edit.php fetch the posted data as:
<?php
if(isset($_POST['submitRooms'])){
#$count = $_POST['count'];
#$srrooms = $_POST['srrooms'.$count];
#$nosrrooms = $_POST['nosrrooms'.$count];
#$nodays = $_POST['nodays'.$count];
echo 'Selected values are: '. $srrooms . $nosrrooms . $nodays;
}
?>
You didn't have added the whole form code so please add the above mentioned form code and the reason why your code is not working is that you haven't added the count with the input field names. And their is no use of fetching the posted data with count in the edit.php till you don't have the input fields named with the $count variable
echo "<input type='hidden' name='srrooms".$count."' value='".$srrooms."' >";
