Question

Imagine that:

A field that could be YES or NO -> Active: Yes | Active: No

So, i got a query that returns it for each client.

I want to show the results in a form, and I should be able to edit that and save on BD again.

I can almost do it, but I need that the default value be wich was already saved on BD, and what I have atm seems show the last row or something.

I want that show the current status or be able to change it for (Yes or NO)

It goes like this for the combobox:

$sql = "SELECT * FROM client,sector WHERE client.idClient = '$id' AND sector.idSector=client.Sector_idSector ";
$result = mysql_query($sql);

while($row = mysql_fetch_array($result))
{

<select name="alterar_sector" id="sectorbox" >
    <?php 
    while($row = mysql_fetch_array($result))
    {
    echo '<option value="'.$row['idSector'].'">'.$row['idSector'].' - '.$row['Nomesec'].'</option>';
    }

    ?>
    </select>

}

Dont give importance of info displayed like “sector” or even the query etc..

Resume:

I want that combobox could display the current value as default and give a list of anothers possible values to change.

Thank you 🙂

I might have missed the point of the question, but are you asking how you can make a from field appear as being selected?
Simple modify this line:

echo '<option value="'.$row['idSector'].'">'.$row['idSector'].' - '.$row['Nomesec'].'</option>';

To have:

echo '<option selected="selected" value="'.$row['idSector'].'">'.$row['idSector'].' - '.$row['Nomesec'].'</option>';

If that is the particular option you want selected…

You might have something like this:

while($row = mysql_fetch_array($result))
{
  if ($sectorActive != $row['idSector']) {
    echo '<option value="'.$row['idSector'].'">'.$row['idSector'].' - '.$row['Nomesec'].'</option>';
  }else{
    echo '<option selected="selected" value="'.$row['idSector'].'">'.$row['idSector'].' - '.$row['Nomesec'].'</option>';
  }
}

Ok, so if you want a select field to have a default value you need to have selected="selected" as a paramater value in the <option> element. As per your example like this:

<select name="gender">
  <option>Male</option>
  <option>Female</option>
  <option selected="selected">Other</option>
  <option>Not Specified</option>
</select>

So if you have a query pulling records and you want to make sure you have the right value selected. You need to have a variable that changes with each record – and you need to install some logic in that HTML insert, like this: (this example will output the same HTML as the example above…)

<?
    $usersGender = 'Other'; // This value should be set via the loop, and from a database value.
?>
<select name="gender">
  <option <?=($usersGender=='Male')?'selected="selected"':''?>>Male</option>
  <option <?=($usersGender=='Female')?'selected="selected"':''?>>Female</option>
  <option <?=($usersGender=='Other')?'selected="selected"':''?>>Other</option>
  <option <?=($usersGender=='Not Specified')?'selected="selected"':''?>>Not Specified</option>
</select>
