Question

I have simple code
File name:newEmptyPHP.php
<form method="post" action="newEmptyPHP.php">Title:
<select name="title">
<option value="select">Select</option>;
<option value="Dr" selected=<?php if(isset($_POST[ 'title'])=="Dr" ){ echo "selected"; } ?>>Dr</option>';
<option value="Prof">Prof</option>';
<option value="Mr">Mr</option>';
<option value="Ms">Ms</option>';
<option value="Miss">Miss</option>';
<option value="Mrs">Mrs</option>';</select>
<input type="submit" value="submit">
</form>
I want to keep selected particular value which was selected before the form submission.
But i did not get the desirable output.
any help appreciated.

Answer 1

change this
<option value="Dr" selected=<?php if(isset($_POST['title']) == "Dr")
{ echo "selected"; } ?> >Dr</option>';
to
<option value="Dr" <?php if(isset($_POST['title']) && $_POST['title'] == "Dr")
{ echo "selected='selected'"; } ?> >Dr</option>';

Answer 2

<?php if(isset($_POST['title']) == "Dr"){ echo "selected"; } ?>
Change to
<?php if(isset($_POST['title']) && $_POST['title'] == "Dr"){ echo "selected"; } ?>
But better to use JS / jQuery. Example for jQuery:
<?php if(isset($_POST['title']) && $_POST['title'] == "Dr"):?>
<script type="text/javascript">
$(function(){
$('select[name=title]').val('<?php echo html_special_chars($_POST[''title'])?>');
});
</script>
<?php endif?>

Answer 3

<?php
if($_POST['title'] == "Dr")
{ ?>
<option value="Dr" selected>Dr</option>
<?php
}
else
{
?>
<?php
<option value="Dr">Dr</option>
<?php
}
?>

Answer 4

Change
<option value="Dr" selected=<?php if(isset($_POST['title']) == "Dr"){ echo "selected"; } ?> >Dr</option>';
To :
<option value="Dr" <?php if(isset($_POST['title']) && $_POST['title'] == "Dr"){ echo 'selected="selected"'; } ?> >Dr</option>';
1.Remove isset where you are checking it for value, isset will return either true or false
2.Make selected="selected inside if condition

Answer 5

There is a mistake in your code. isset(Something) will return either true or false and will not return Dr you are looking for.
Retry with this
<form method="post" action="newEmptyPHP.php">
Title:<select name="title" >
<option value="" >Select</option>
<option value="Dr" selected=<?php if(isset($_POST['title']) && $_POST['title'] == "Dr"){ echo "selected"; } ?> >Dr</option>';
<option value="Prof" <?php if(isset($_POST['title']) && $_POST['title'] == "Prof"){ echo "selected"; } ?>>Prof</option>';
<option value="Mr" <?php if(isset($_POST['title']) && $_POST['title'] == "Mr"){ echo "selected"; } ?>>Mr</option>';
<option value="Ms" <?php if(isset($_POST['title']) && $_POST['title'] == "Ms"){ echo "selected"; } ?>>Ms</option>';
<option value="Miss" <?php if(isset($_POST['title']) && $_POST['title'] == "Miss"){ echo "selected"; } ?>>Miss</option>';
<option value="Mrs" <?php if(isset($_POST['title']) && $_POST['title'] == "Mrs"){ echo "selected"; } ?>>Mrs</option>';
</select>
<input type="submit" value="submit">

Answer 6

I thin you have static option values.If so the you have to check for every option like as below for one.
<form method="post" action="newEmptyPHP.php">
Title:<select name="title" >
<option value="select" >Select</option>;
<?php
$selected = "";
if(isset($_POST['title']) && $_POST['title'] == "Dr")
{
$selected = 'selected="selected"';
}
?>
<option value="Dr" <?php echo $selected; ?>>Dr</option>
<option value="Prof">Prof</option>
<option value="Mr">Mr</option>
<option value="Ms">Ms</option>
<option value="Miss">Miss</option>
<option value="Mrs">Mrs</option>
</select>
<input type="submit" value="submit">
</form>

Answer 7

I would rather prefer this code for the purpose
$option_array = array('select'=>'select','mr'=>'mr'... other values);
<?php
$option_string = '';
foreach($option_array as $key=>$value)
{
if($key == $_POST['title'])
{
$selected = 'selected';
}
else
{
$selected = '';
}
$option_string .= "<option value='$key' $selected>$value</option>";
}
?>
<form method="post" action="newEmptyPHP.php">Title:
<select name="title">
<?php echo $option_string; ?>
</select>
<input type="submit" value="submit">
