I have a SET field in MYSQL.
'1. Type One','2. Type Two','3. Type Three'
The user can multi-select
<select name="DPRtype[]" multiple>
<option value="1. Type One">
<option value="2. Type Two">
<option value="3. Type Three">
</select>
I just dont know how to express $_POST[DPRtype] to be able to build the $SQL to express the separate possibilities.
$sql = "UPDATE taylorjo.CRTP_CGA
SET
DPRtype = '$_POST[DPRtype]'
";
If I use a foreach like this, it will be very clunky. And I'll have an extra comma at the end. What is a cleaner way?
$MyString = express_value_select ($_POST['DPRtype'],"1. Type One");
$MyString .= express_value_select ($_POST['DPRtype'],"2. Type Two");
$MyString .= express_value_select ($_POST['DPRtype'],"3. Type Three");
function express_value_select($tofilter,$tofind) {
foreach($tofilter as $value){
if ($value == $tofind) echo $tofind.",";
}
}
foreach($_POST['DPRtype'] as $row){
echo $row. ",";
}
Then trim a comma?
