[RESOLVED] Question about dropdown combo

Hi all I have a question regarding with dropdown combo. May I know how to view back the data at dropdown combo so that I can edit it?

Example here:
I have saved the data about my personal. In that form I have selected the wrong country. Then I want to view this data to edit the country. What I cannot do is I want to display the previous country that I selected before at that dropdown combo. Can someone please tell me the simple way how to do it?

Thanks

If it's stored in a database you could do something like this: (I assume you're only having problems making the current country display as 'selected' in the option values) I also don't know how you're listing your countries, so I put some in an array. just a few though.

PHP Code:

---

<select name="country"><?php
  @extract(mysql_fetch_assoc(mysql_query("SELECT country as thiscountry FROM table_name WHERE username='test' LIMIT 1")));
  if(isset($thiscountry)){
    $countries = array("Canada", "United States", "Vietnam", "Japan", "Russia", "France", "England", "Germany", "Egypt", "Chad", "Afghanistan", "Iraq", "Mexico");
    sort($countries)
    foreach($countries as $country){
?>
  <option value="<?php echo $country; ?>"<?php if($country == $thiscountry) echo ' selected="selected"'; ?>><?php echo $country; ?></option>
<?php
    }
  }
?>
</select>

This should properly highlight the user's current country when loading the page.

Thanks a lot Mr.Kows for always answered me..but i dont understand your coding.I pulled the country name from database..this is my codes..hope you can help me.

PHP Code:

---

<select name="country">
<option>Select Country</option>
<? 
    $query=mysql_query("SELECT * FROM Country ORDER BY country_name");
    while($edit=mysql_fetch_array($query))
    {?>
    <option value="<? echo $edit['country_id']?>">
    <? echo $edit['country_name']?>
    </option>
    <? 
    }    
    ?>

</select>

Thanks in advance

it probably isn't working simply because you have a line break after the <option> and before the </option>. It doesn't support multiple lines, so it's most likely just displaying blank. Try changing it to:

PHP Code:

---

 <select name="country">
<option>Select Country</option>
<? 
    $query=mysql_query("SELECT * FROM Country ORDER BY country_name");
    while($edit=mysql_fetch_array($query))
    {?>
    <option value="<? echo $edit['country_id']?>"><? echo $edit['country_name']?></option>
    <? 
    }    
    ?>
</select>

Thanks a lot Mr.Kows

I got the solution now..but it is not working properly..
i can display the country data in dropdown in Edit form.
But if the country no need to change, it will return empty data after i hit Edit Button.
I must always select the country in dropdown even i dont want to edit that.
Here is my codes..please let me know how to settle this problem..thanks

PHP Code:

---

<select name="country">
<option selected value="<? echo $country ?>"><? if($country!=""){echo $country;} else {echo "";} ?></option>
<option value="">-------------</option>
 <?
$sqlst = mysql_query("SELECT * FROM Country ORDER BY country_name");
while($coun = mysql_fetch_array($sqlst)){ ?>
<option value="<? echo $coun['country_id'] ?>"><? echo $coun['country_name'] ?>
</option>
<? } ?>
</select>

you can simply rearrange the code you already have into something that will work correctly for you.

PHP Code:

---

<select name="country">
<option value="">-------------</option>
 <?
$sqlst = mysql_query("SELECT * FROM Country ORDER BY country_name");
while($coun = mysql_fetch_array($sqlst)){ ?>
<option value="<? echo $coun['country_id'] ?>"<?php if($coun['country_name'] == $country) echo ' selected="selected"'; ?>><? echo $coun['country_name'] ?>
</option>
<? } ?>
</select>

I'm not sure if $country holds the name of the country or the ID (BUT, I assume it holds the name judging by the code you've provided), so you can change the statement I added to fit your needs better (to either $coun['country_id'], or keep it as $coun['country_name'])

hope that helps.

edit: also, I think the reason why yours kept submitting as blank was because you're defining your <option>'s value attribute as a string ($country) instead of a number (the country ID). I assume this is what is giving you the problem you had, but the code I posted above will fix this for you.
