Hi All,

 

I am having some trouble with my drop down menus.

 

I would like it so when the user submits the form and the errors pop up after the form refreshes the drop down options that the users entered stay selected, rather than revert to default.

 



<?php include('menu.php'); ?>

<?php
require_once('calendar/calendar/classes/tc_calendar.php');
?>


<?php 
/*  
NEW.PHP 
Allows user to create a new entry in the database 
*/ 
  
// creates the new record form 
// since this form is used multiple times in this file, I have made it a function that is easily reusable 
function renderForm($asset_tag, $asset_type, $model, $sku, $warrenty_expiry_date, $purchase_date, $serial_number, $location, $practice, $user_name, $mobile_number, $network, $po_number, $cost, $username, $input_date, $ram, $make, $processor, $operating_system, $hd_gb, $screen_size, $error, $error_2, $error_3, $error_4, $error_5, $error_6, $error_7) 
{ 
?>

I would add there information to sessions. So it will be there on screen reload. but you can use $_POST also.

acctually im not really sure untested but really you should beable to use $_POST['username_1']; so you dont even have to save it to a variable

 

$_SESSION['username'] = $_POST['username_1'];

 

 

 

<select name="username_1">

<option value="John" <?php echo $_SESSION['username'] == 'John' ? 'selected="selected"' : ''; ?>
>John</option>

</select>

 

what this is saying is that if their user name equals what any of the ones in the drop down box then display it as selected

Thanks for your reply Shadowing.

 

Will I be able to implement your last suggestion: 

<select name="username_1"><option value="John" <?php echo $_SESSION['username'] == 'John' ? 'selected="selected"' : ''; ?> >John</option></select>

 

The reason being that the options that I am derriving come from the database and are not listed in the code.

 

<?php          // connect to the database         include('config.php'); $result=mysql_query("select username from test"); $options=""; while ($row=mysql_fetch_array($result)) {     $categoryname=$row["username"];     $options.="<OPTION VALUE=\"$categoryname\">".$categoryname.'</option>'; } ?>         <select name="username_1">           <option >SELECT<?php echo $options ?></option>}?>

 

Any more ideas?

 

Many thanks

 

MC

Still use the above example but instead of string use the variable

 

foreach ($results as $single_result) {
echo '<option value=".$single_result['select_field'].'"';
if ($_SESSION['val'] === $single_result['select_field']) {
echo ' selected="selected"';
}
echo '">'.$single_result['text_field'].'</option>';

}

 

 

// Sorry to lazy to actually read your code for exact copy and paste but should help

Just to be clear as to what you are needing

 

you want it so that when the user hits submit the page reloads stores data from a input field into the data base and it shows what he chose? And you want it to always show what he has chosen every time he comes back to that page?

 

 

If that is right then you will have to query what he has in the data base.

i assume your users have a session id right? So when the screen reloads it grabs the data out of the database and displays it as selected

 

$results= "SELECT username FROM table WHERE user_id = '".($_SESSION['user_id'])."'"; 
$msql= mysql_query($results) or die(mysql_error());
$fetch = mysql_fetch_assoc($msql);

<select name="username_1"><option value="John" <?php echo $fetch['username']
== 'John' ? 'selected="selected"' : ''; ?> >John</option></select>

Thanks for your help chaps - much appreciated.

 

I have been wrestling with this piece of code all day, and am having trouble implementing onlyican's code..

 

<?php  

        // connect to the database 
        include('config.php'); 

$result=mysql_query("select username from test"); 
$options=""; 
while ($row=mysql_fetch_array($result)) { 

    $categoryname=$row["username"]; 
    $options.="<OPTION VALUE=\"$categoryname\">".$categoryname.'</option>'; 
} 

?>

         <select name="username_1">
           <option >SELECT<?php echo $options ?></option>


foreach ($results as $categoryname) {
echo '<option value=".$categoryname['username'].'"';

if ($_POST['username_1'] === $categoryname['username']) {
echo ' selected="selected"';

}

echo '">'.$categoryname['text_field'].'</option>';

}

 

 

 

Any hints? or am I going completly off track with this one!

 

Please excuse me if I have made a blaring mistake, as I am still a novice at php!

 

Cheers
