So I am building an example search page with PHP. It is a job search page with several web forms. When one of these is submitted I want to be able to save the values. I am trying to save them in a session variable and reload the select list, however I can't get it to work. Anyone know what I am doing wrong? Here is my code:
<!DOCTYPE html>
<?php
session_start();
if(isset($_POST['occupation']))
$_SESSION['occupation'] = $_POST['occupation'];
if(isset($_POST['work_type']))
$_SESSION['work_type'] = $_POST['work_type'];
if(isset($_POST['sort_by']))
$_SESSION['sort_by'] = $_POST['sort_by'];
?>
<html>
<head>
<style>
table
{
width: 50%; margin: 0 auto;
}
.td-left
{
width: 20%;
}
</style>
</head>
<body>
<table>
<tr>
<td class="td-left" valign="top">
<form method="post" action="">
<h2>Keyword</h2>
<input type="text" name="keyword"/>
<h2>Industy</h2>
<select name="occupation[]" multiple >
<?php
$occ = array("Accounting", "Education", "Healthcare", "Information Technology", "Retail", "Sales");
$len = count($occ);
for($i = 0; $i<$len; $i++ )
{
if(in_array($occ, $_SESSION['occupation']))
echo '<option value="' . $i . '" selected>' . $occ[$i] .'</option>';
else
echo '<option value="' . $i . '" >' . $occ[$i] .'</option>';
}
?>
</select>
<br/><br/>
<button type="submit" value="Search" class="my-button" name="search_button" >Search</button>
</form>
</td>
<td style="float: right; " valign="top">
<form method="post" action="">
<h2>Sort By</h2>
<select name="sort_by" onchange="this.form.submit()" >
<?php
$sort_types = array("Date posted descending", "Date posted ascending", "Job title descending", "Job title ascending", "Location descending", "Location ascending", "Salary descending", "Salary ascending" );
$len = count($sort_types);
for($i = 0; $i<$len; $i++ )
{
if(in_array($sort_types, $_SESSION['sort_by']))
echo '<option value="' . $i . '" selected>' . $sort_types[$i] .'</option>';
else
echo '<option value="' . $i . '" >' . $sort_types[$i] .'</option>';
}
?>
</select>
</form>
</td>
</tr>
<tr>
<td class="td-left" valign="top">
<form method="post" action="" name="refine_search">
<h2>Refine Search</h2>
<select name="work_type[]" multiple >
<?php
$wt = array("Full Time", "Part Time", "Casual");
$len = count($wt);
for($i = 0; $i<$len; $i++ )
{
if(in_array($wt, $_SESSION['work_type']))
echo '<option value="' . $i . '" selected>' . $wt[$i] .'</option>';
else
echo '<option value="' . $i . '" >' . $wt[$i] .'</option>';
}
?>
</select>
<br/><br/>
<button type="submit" value="Go" class="my-button" name="refine_search_button">Go</button>
</form>
</td>
<td valign="top">
<h2>Results</h2>
Lorem Ipsum Dolor Sit Amet ...
</td>
</tr>
</table>
</body>
</html>
Correct syntax for in_array is in_array(search,array,type) So :
in_array($_SESSION['work_type'], $wt)
