Question

I am using Jquery Multiselect Widget to have a dropdown list box with mulitselect option. I am populating the dropdown with the data from MySql database. I was not able to pass multiple values to the php file in $_POST.

My HTML & PHP code for Multiselect DropDown.

   <form id="intermediate" name="inputMachine" method="post">

<select id="selectDuration" name="selectDuration" multiple="multiple"> 
  <option value="1 WEEK" >Last 1 Week</option>
  <option value="2 WEEK" >Last 2 Week </option>
  <option value="3 WEEK" >Last 3 Week</option>
</select>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;


    <?php
        //include '../db/interface/DB_Manager.php';
        $connect = mysql_connect("localhost", "root", "infinit") or die(mysql_error()); 
        mysql_select_db("serverapp") or die(mysql_error()); 

        $query = "select id,name from rpt_shift_def"; //Write a query
        $data = mysql_query($query);  //Execute the query
    ?>
    <select id="selectShift" name="selectShift" multiple="multiple">
    <?php
    while($fetch_options = mysql_fetch_array($data)) { //Loop all the options retrieved from the query
    ?>

    <option name="selected_ids[]" id ="<?php echo $fetch_options['id']; ?>"  value="<?php echo $fetch_options['name']; ?>"><?php echo $fetch_options['name']; ?></option><!--Echo out options-->
    <?php
        }
    ?>
    </select>

Here i’m populating Shift dropdown in Multiselect Dropdown. If i select more than one shift, i was not able to get all those selected values in php. instead i get only the last selected value.

i want to do something like this.

   $shiftarraycalc = array();

foreach ($_POST['selectShift'] as $key => $value) {
    array_push($shiftarraycalc,$value);
}

but its not working.

I have no idea how to get multiple values in $_POST.

Answer 1

Modified name as array in select

<select id="selectShift" name="selectShift[]" multiple="multiple">

and did like this and it works

$shiftarraycalc = array();
$shift=$_POST['selectShift'];

if ($shift)
{
    foreach ($shift as $value)
    {
        array_push($shiftarraycalc,$value);
    }
}
