You need to add the "selected" attribute to the appropriate option. I believe you also need to specify the value attribute for each option. I don't know exactly how you are generating that list, but maybe this will help:
<?php $options = array( 1=>'General Question', 'Company Information', 'Customer Issue', 'Supplier Issue', 'Supplier Issue', 'Request For Quote', 'Other' ); $topic = $_REQUEST['topic']; // the topic name would now be $options[$topic] // other PHP etc... ?> <select name="topic" style="margin-bottom:3px;"> <?php foreach ( $options as $i=>$opt ) : ?> <option value="<?php echo $i?>" <?php echo $i == $topic ? 'selected' : ''?>><?php echo $opt ?></option> <?php endforeach; ?> </select>讨论(0) -
First of all, give the option element a value attribute. This makes the code more robust, because it does not break should you decide to alter the text of an option. After that:
<?php $topic = $_REQUEST['topic']; ?> <?php $attr = 'selected="selected"'; ?> <select name="topic" style="margin-bottom:3px;"> <option value="1" <?php echo $topic == 1 ? $attr : ''; ?>>General Question</option> <option value="2" <?php echo $topic == 2 ? $attr : ''; ?>>Company Information</option> <option value="3" <?php echo $topic == 3 ? $attr : ''; ?>>Customer Issue</option> <option value="4" <?php echo $topic == 4 ? $attr : ''; ?>>Supplier Issue</option> <option value="5" <?php echo $topic == 5 ? $attr : ''; ?>>Request For Quote</option> <option value="6" <?php echo $topic == 6 ? $attr : ''; ?>>Other</option> </select>讨论(0)
