Using Php $_post To Remember A Option In A Select Box?

I have a form which POSTs to itselft so the user can do things that you would find in a Shopping Cart. e.g. Increase quantity, select postage type. My problem is for my form Select

Solution 1:

You almost got it. You need to set the attribute selected="selected" (the exact form you need technically depends on your HTML doctype, but this is a safe default) on the <option> element if and only if the value of $postage equals the value of the element. So:

<selectname="postage"><optionvalue="foo"<?phpif ($_POST['postage'] == "foo") echo'selected="selected" '; ?>
 ></select>

Note that this violates the DRY principle because you now have two occurrences of the string "foo" in there, so it's a prime candidate for refactoring. A good approach would be to keep value/text pairs in an array and iterate over it with foreach to produce the <option> tags.

Solution 2:

You need to foreach through all the options.

Make an array with all the dropdown options, loop through that, and compare with what is stored in post.

E.G.:

<?php$aDropd = array("apple","orange","banana");
echo"<select>";
foreach($aDropdas$sOption){
  $sSel = ($sOption == $_POST['postage'])? "Selected='selected'":"";
  echo"<option   $sSel>$sOption</option>";
}
echo"</select>";

Solution 3:

no its not working at all..you need to put some kind of loop for that.

For Example : foreach($record => $values){
                   if($values == $_POST['postage']){
                       $selected = "selected='selected' ";
                      }else{
                       $selected = "";
                      }
             }

<input name="postage" value="1"<?=$selected?> >

EDITED:

if($_POST['postage'] == 1){
                           $selected1 = "selected='selected' ";
                          }elseif($_POST['postage'] == 2){
                           $selected2 = "selected='selected' ";
                          } and so on..........



    <select name="postage">
     <option value="1"<?=$selected1;?> />
     <option value="2"<?=$selected2;?> />
    </select>

I think this may be helpful to you..you can ask me if anything else needed...

Thanks.

Solution 4:

The value of selected should be selected

<selectname="postage"value="1"<?phpecho (($_POST['postage'] == 1)?'selected="selected"':''); ?> >

Solution 5:

Your html syntax is wrong. The correct way to write the html is like this:

<select><optionvalue ="<?phpecho$_POST['postage']; ?>"selected="selected"></option></select>
