Loading ...We need to populate dropdown fields from Mysql SET or ENUM fields pretty often. So here is how I use to do it.
Lets say ‘test’ is a table that has a field, ‘agree’ of type ‘SET’ having values ‘Yes’ and ‘No’. On the front end of my application I want to show a dropdown/select field having options ‘Yes’ and ‘No’.
First get the field’s ‘SET’ values. This is a function I wrote for myself to get the ENUM field values.
function getEnumFieldValues($tableName, $fieldName){
$field_query = mysql_query("show columns from $tableName where Field='$fieldName'");
if(mysql_num_rows($field_query) <= 0) return false;
$fieldDetail = mysql_fetch_array($field_query);
$type = preg_replace('/(^set\()|(^enum\()/i', '', $fieldDetail['Type']);
$enumFields = substr($type, 0, -1);
$fieldSplit = split(',', $enumFields);
return $fieldSplit;
}
Using the values, populate the dropdown field like this.
$enumFields = getEnumFieldValues('agree', 'test');
echo '<select name="agree">';
foreach($enumFields as $value){
echo '<option value="' . $value . '">' . $value . '</option>';
}
echo '</select>';
That's all. Now put any table and field names to get the ENUM/SET field values and create your dropdown.

Handling quotes is always a bit tricky. You need to convert quotes to html entities, which means use the code like following:
$enumFields = getEnumFieldValues('agree', 'test'); echo '<select name="agree">'; foreach($enumFields as $value){ echo '<option value="' . htmlentities($value) . '">' . $value . '</option>'; } echo '</select>';When you are using the submitted value in your php script, get the value like this:
$value = html_entity_decode($value);
Hope this helps.
