I created a function in php, my goal with this function is to print the following line in a HTML select tag.
<option value="<?php echo $key . $product[$name . '_id'] == $key ? 'selected' : null ?>"><?php echo $value ?></option>
This is what I've come up with:
function Select($name){
$ids = array();
$values = array();
$query1 = $sql->query("SELECT * FROM '$name'");
while($fetch = $query1->fetch_assoc()){
array_push($ids, $fetch[$name . '_id']);
array_push($values, $fetch[$name]);
}
$names = array_combine($ids, $values);
foreach($names as $key => $value){
return '<option value="' . $key . '"' . $product[$name . '_id'] == $key ? 'selected' : null . '>' . $value . '</option>';
}
}
This does not seem to work, however when I put this directly in the HTML select tag it does work. It looks like this:
<select name="type" class="chozen" id="type">
<?php
$brand_ids = array();
$brand_values = array();
$query1 = $sql->query("SELECT * FROM brands");
while($brand = $query1->fetch_assoc()){
array_push($brand_ids, $brand['brand_id']);
array_push($brand_values, $brand['brand']);
}
$brands = array_combine($brand_ids, $brand_values);
foreach($brands as $key => $value){
?>
<option value="<?php echo $key ?>"<?php echo $product['brand_id'] == $key ? 'selected' : null ?>><?php echo $value; ?></option>
<?php
}
?>
</select>
Can someone point me where I went wrong, I can not figure it out.
Your problem is that you're trying to return every single line separately. But your function won't continue after first return. this should work:
$str = '';
foreach($names as $key => $value){
$str = $str.'<option value="' . $key . '"' . $product[$name . '_id'] == $key ? 'selected' : null . '>' . $value . '</option>';
}
return str;
$brands = array() ;
$query1 = $sql->query("SELECT * FROM brands");
while($brand = $query1->fetch_assoc()){
$brands[$brand['brand_id']] = $brand ; //Just use brand_id as keys in the array
}
if (!empty($brands)): ?>
<select name="type" class="chozen" id="type">
<?php foreach($brands as $id => $brand): ?>
<option value="<?php echo $brand['brand'] ; ?>"<?php echo ($brand['brand_id'] == $id ? 'selected' : ""); ?> ><?php echo $brand['brand'] ; ?></option>
<?php endforeach ; ?>
</select>
<?php else : ?>
<div>No brands to display!</div>
<?php endif ; ?>
I think you can try the following line:
$str = "";
foreach($names as $key => $value){
$str .= '<option value="' . $key . '" ' . (($product[$name . '_id'] == $key) ? 'selected' : '') . '>' . $value . '</option>';
}
return $str;
1) use empty string instead of null. 2) Space after $key in value
hopefully it help
