Closed 6 years ago.
I have an issue where by I want to save a user input and then allow them to edit it later.
when i list the results for the edit their is no default.
<select id="edit_group" name="edit_group" class="form-control">
<?php Types("") ?>
</select>
types function is
function Types($x){
global $mysqli;
$type = " SELECT type FROM types ";
if ($type_results = $mysqli->query($type)) {
while ($row = $type_results->fetch_assoc()) {
printf ("<option>%s</option>", $row["type"]);
}
$type_results->free();
}
}
if anyone could point me in the right direction of how i could set the default value so its the one stored in the db, it would really help a beginner out. or better still point me in the right direction of documentation as my google searches have returned nothing but json and java options.

You don't use an argument $x of your Types function which as i guess is a selected value. Try to replace your function with this code:
function Types($x) {
global $mysqli;
$type = " SELECT type FROM types ";
if ($type_results = $mysqli->query($type)) {
while ($row = $type_results->fetch_assoc()) {
$selected = ($row["type"] == $x) ? 'selected="selected"' : '';
printf ("<option %s>%s</option>", $selected, $row["type"]);
}
$type_results->free();
}
}
and of course provide selected value to function Types in your html code.
