I have been working on a site however i can't seem to find the answer to this question. I have a drop down box which is pulling data from table info_weapons_manafacture. Here is the table layout.
--
-- Table structure for table `info_weapons_manafacture`
--
DROP TABLE IF EXISTS info_weapons_manafacture;
CREATE TABLE `info_weapons_manafacture` (
`id` int(11) NOT NULL,
`info_weapons_manafacture_name` varchar(255) NOT NULL,
`info_weapons_manafacture_abbreviation` varchar(255) NOT NULL,
`info_weapons_manafacture_description` varchar(255) NOT NULL,
`info_weapons_manafacture_founded` varchar(255) NOT NULL,
`info_weapons_manafacture_headquarters` varchar(255) NOT NULL,
`image` varchar(255) NOT NULL,
`created_at` timestamp NOT NULL DEFAULT current_timestamp()
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;
Here is the Table for Manafactures;
--
-- Table structure for table `info_weapons_manafacture`
--
DROP TABLE IF EXISTS info_weapons_manafacture;
CREATE TABLE `info_weapons_manafacture` (
`id` int(11) NOT NULL,
`info_weapons_manafacture_name` varchar(255) NOT NULL,
`info_weapons_manafacture_abbreviation` varchar(255) NOT NULL,
`info_weapons_manafacture_description` varchar(255) NOT NULL,
`info_weapons_manafacture_founded` varchar(255) NOT NULL,
`info_weapons_manafacture_headquarters` varchar(255) NOT NULL,
`image` varchar(255) NOT NULL,
`created_at` timestamp NOT NULL DEFAULT current_timestamp()
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;
Now the drop down box is populating with the values, but in order to make the drop down box show the value from the database we post this code.
<label for="Characterimage" class="col-lg-2 col-form-label tits">Manafacture:</label>
<select class="form-control form-control-sm col-lg-10" id="js-choose" name="info_weapon_manafactureID" style="height: 40px">
<?php $manafacture_id = $r['info_weapon_manafactureID'];
$q2 = $db->query("SELECT * FROM info_weapons_manafacture WHERE id = '$manafacture_id'");
($r2 = $q2->fetch(PDO::FETCH_ASSOC));
if($r2['image']){?>
<option value="<?= $r2['id']; ?>" data-img="uploads/<?= $r2['image']; ?>"><?= $r2['info_weapons_manafacture_name']; ?></option>
<?php }else{ ?>
<option value="<?= $r2['id']; ?>" data-img="<?= ASSETS ?>img/no-image.png"><?= $r2['info_weapons_manafacture_name']; ?></option>
<?php } } ?>
<?php
$q5 = $db->query("SELECT * FROM info_weapons_manafacture");
while ($r5 = $q5->fetch(PDO::FETCH_ASSOC)) {
if($r5['image']){?>
<option value="<?= $r5['id']; ?>" data-img="uploads/<?= $r2['image']; ?>"><?= $r5['info_weapons_manafacture_name']; ?></option>
<?php }else{ ?>
<option value="<?= $r5['id']; ?>" data-img="<?= ASSETS ?>img/no-image.png"><?= $r5['info_weapons_manafacture_name']; ?></option>
<?php } ?>
<script>
jQuery.fn.uniqueAttrs = function(attr) {
if(!attr) return this;
var that = this;
return this.filter(function (index, node) {
return that.index(that.filter(function() {
return this[attr] === node[attr];
})) === index;
});
};
var $ul = $('#js-choose');
$ul.html($ul.find('option').uniqueAttrs(<?= $r5['info_weapons_manafacture_name']; ?>));
</script>
<?php } ?>
</select>
However this is making it so that the value in the drop down box is repeating the one that is in the database, i was wondering if there is a way to highlight the value that is in the record while also not having a duplicate value in the list...
Thanks in Advance.. :)
