如何在“编辑”表单中自动选择值？

Question

Can you help me to correct this code

<select name="ClassHall">
    <?php
    while ($Hall = mysql_fetch_array($resultHall, MYSQL_ASSOC)) {
    ?>
    <option value="<?php echo $Hall['HallName'];?>"

    <?php if($ClassHall == '$Hall['HallName']'){ echo(' selected '); } ?>

     > <?php echo $Hall['HallName'];?> </option>

    <?php
    }
    ?>
</select>

I would like to auto select the value in Edit form. It have syntax error in '$Hall['HallName']' part.

You have the variable in a singlequotes on this line:

 <?php if($ClassHall == '$Hall['HallName']'){ echo(' selected '); } ?>

Try changing that to something like:

 <?php if($ClassHall == $Hall['HallName']){ echo(' selected '); } ?>
