动态下降问题在Php

Question

I have a dynamicdrop down, I am fetching options dynamically. Below is the code but option "selected" is not working in spite of giving it in first HTML tag. I want Select Category to be selected by default on page load.

My PHP code:

<?php  $decode = json_decode($str_json_format, TRUE); ?>
<select name="category" id="category" tabindex="6"> 
    <option value="1" selected>Select category</option>    
        <?php foreach($decode as $key => $value) { ?>
            <option value="<?php echo $value['category_id']; ?>"><?php echo $value['name']; ?></option>
        <?php } ?>
</select>

Answer 1

Remove selected from first Option:

<?php  $decode = json_decode($str_json_format, TRUE);   ?>
<select name="category" id="category" tabindex="6"> 
    <option value="1">Select category</option>    
     <?php foreach($decode as $key => $value) { ?>
         <option value="<?php echo $value['category_id']; ?>"><?php echo $value['name']; ?></option>
      <?php } ?>
   </select>
