Question

I am looking for some method to select a php combobox “<select>” based on results from mysql.

Actually I am working on a php form that will be used to edit existing values in mysql table. My first form will simply pass the id of the record to be edited, and this goes something like this <a href=”editCalendar.php?id=15″>Click to edit</a>

Code on editCalendar.php is as follows:

<?php
    include("dbpath.php");
    $id =  htmlspecialchars($_GET["id"]);

    $sql="Select * from event_Date where eventid=" . $id;
    $result=mysql_query($sql);

    // Check result
    // This shows the actual query sent to MySQL, and the error. Useful for debugging.
    if (!$result) 
    {
        $message  = 'Invalid query: ' . mysql_error() . "\n";
        $message .= 'Whole query: ' . $query;
        die($message);
    }

    while($row = mysql_fetch_assoc($result))
    {
    $name=$row["EventTitle"];
    $close=$row["OpenOrClose"];
    $remarks=$row["Remarks"];
    $date=$row["EventDate"];
    $type=$row["Type"];
    }
?>

The value obtained in $close will be used to select “SelectClosedOrOpen” on the same form, i.e. the user will get pre selected option from the populated list.

<select id="SelectClosedOrOpen">
<option value="3">Select</option>
<option value="0">Open</option>
<option value="1">Closed</option>
</select>

Means, if $close has 0, then <option value="0">Open</option> must be selected else if $close has 1 then <option value="1">Closed</option> should be automatically selected on formload.

You’ll just need to write the selected attribute in there. Try this

<select id="SelectClosedOrOpen">
<option value="3" <?php echo ($close == 3) ? 'selected="selected"': ''; ?>>Select</option>
<option value="0" <?php echo ($close == 0) ? 'selected="selected"': ''; ?>>Open</option>
<option value="1" <?php echo ($close == 1) ? 'selected="selected"': ''; ?>>Closed</option>
</select>
