I like do multiple select option using PHP , but i am unable to do multiple select.
this is my code
<?
include_once("common.php");
$iCompanyId = isset($_REQUEST['company'])?$_REQUEST['company']:'';
$iDriverId = isset($_REQUEST['iDriverId'])?$_REQUEST['iDriverId']:'';
$selected = "selected";
if($iCompanyId != '')
{
$sql = "select * from register_driver where iCompanyId = '".$iCompanyId."' and eStatus != 'Deleted'";
$db_model = $obj->MySQLSelect($sql);
$cont = '';
$cont .= '<select multiple class="validate[required] form-control" id="iDriverId1" name="iDriverId">';
$cont .= '<option value="">CHOOSE DRIVER </option>';
for($i=0;$i<count($db_model);$i++){
if($db_model[$i]['iDriverId'] == $iDriverId)
$cont .= '<option value="'.$db_model[$i]['iDriverId'].'" '.$selected.'>'.$db_model[$i]['vName'].' '.$db_model[$i]['vLastName'].'</option>';
else
$cont .= '<option value="'.$db_model[$i]['iDriverId'].'">'.$db_model[$i]['vName'].' '.$db_model[$i]['vLastName'].'</option>';
}
$cont .= '</select>';
echo $cont; exit;
}
?>
Use 'selected Attribute' like
if(condition) { <option value="" selected> test</option>

I know only this method. this method is assume that you know the values in all <option>
<select name="agama" id="agama">
<option value="Islam"<?php if ($rows['agama'] === 'Islam') echo ' selected="selected"'>Islam</option>
<option value="Khatolik"<?php if ($rows['agama'] === 'Khatolik') echo ' selected="selected"'>Khatolik</option>
<option value="Protestan"<?php if ($rows['agama'] === 'Protestan') echo ' selected="selected"'>Protestan</option>
<option value="Hindu"<?php if ($rows['agama'] === 'Hindu') echo ' selected="selected"'>Hindu</option>
<option value="Buddha"<?php if ($rows['agama'] === 'Buddha') echo ' selected="selected"'>Buddha</option>
<option value="Lain-Lain"<?php if ($rows['agama'] === 'Lain-Lain') echo ' selected="selected"'>Lain-Lain</option>
</select>
.... the above code is example from other people not mine.
but My case is the <option> is select from database too.
I have 2 table, oav_event and oav_album
the oav_album has foreign key (event_id) from oav_event table
I want to check if row['event_id'] from oav_album table is equal to option value (from oav_event table) if true, then set selected="selected"
while($row = mysqli_fetch_assoc($result)) { ?>
<option value="<?php echo $row['event_id']; ?>" >Event: <?php echo $row['event_date']; ?> </option>
<?php } ?>
the option will change depend on change in database table, so I don't know the value in option. How should I do?
<select name="event_id">
<?php
$sql = "SELECT * FROM oav_event";
$result = mysqli_query($conn, $sql);
while($row = mysqli_fetch_assoc($result)) {
$selected = "";
if($row['event_id'] == $Yourmatchvalue)
{
$selected = "selected";
}
?>
<option value="<?php echo $row['event_id']; ?>" selected="<?php echo $selected; ?>" >Event: <?php echo $row['event_date']; ?> </option>
<?php } ?>
</select>
may this helps your. you need to replace $Yourmatchvalue variable with your variable.
You can use $_GET as the method on your form and pass the id of the record using it:
while($row = mysqli_fetch_assoc($result)) {
if (!empty($_GET['event_id']) && $row['event_id'] == $_GET['event_id']) {
$selected = 'selected = "selected"';
} else {
$selected = '';
}
echo '<option '.$selected.' value="'.$row["event_id"].'">'.$row["event_date"].'</option>';
}
Here is a solution,
$selected_value = 'Hindu'; // This will come from database
Change option tag with this
<option value="<?php echo $row['event_id']; ?>" <?php echo ($row['event_id'] == $selected_value) ? 'selected="selected"' : ''; ?> >Event: <?php echo $row['event_date']; ?> </option>
Create one function which will create options list like this:
function setDropdownValue($selectQueue_list,$selectedVal)
{
$queueVal = '';
$selectQueue_list_res=$db->query($selectQueue_list);
while($selectQueue_list_res_row=$db->fetchByAssoc($selectQueue_list_res))
{
$val = $selectQueue_list_res_row['id'];
$name = $selectQueue_list_res_row['name'];
if($val == $selectedVal)
{
$queueVal .= "<option value='$val' selected='selected' label='$name'>$name</option>";
}
else
{
$queueVal .= "<option value='$val' label='$name'>$name</option>";
}
}
return $queueVal;
}
Then create a query:
$get_value_query="SELECT id, name FROM table";
$dropdown_selected_value = !empty($dropdown_value) ? $dropdown_value: ''; // Pass value which you want to be selected in dropdown
Then call this function:
$dropdown_options = setDropdownValue($get_value_query, $dropdown_selected_value);
Later when you get dropdown options in $dropdown_options, use jquery to populate the dropdown, like this:
$('#dropdown_select_id').html("$dropdown_options");
Give it a try, and let me know.
how to fix this syntax for this logic ?
i want to select my select option to select the another select option
<?php
$query_string = "SELECT * FROM products";
$query_string1 = "SELECT * FROM suppliers where ProductID = // firstSelectoption(value)";
$query_string2 = "SELECT * FROM categories";
$query = mysql_query($query_string);
$query1 = mysql_query($query_string1);
$query2 = mysql_query($query_string2);
?>
and in the body i make
<select name="first" id="first" onchange="childrenOnChange(this.value)">
<?php
while ($row = mysql_fetch_array($query)) {
echo '<option value=' . $row["ProductID"] . '>';
echo $row['ProductID'];
echo '</option>';
}
?>
</select>
<select name="second" id="second">
<?php
while ($row = mysql_fetch_array($query1)) {
echo '<script>';
echo 'var arr = array(';
$row['SupplierID'] . ',';
echo ')';
echo '</script>';
}
?>
</select>
i want to set the second select option value with $query1;
If you get the value from the query with $val = mysql_fetch_array($query1), then you can include the following in your loop:
$selected = '';
if ($row['ProductID'] == $val) {
$selected = "selected";
}
echo '<option value="'.$row['ProductID'].'" '.$selected.'>'.$row['ProductID'].'</option>';
I have a dropdown in my form, In which data is being fetch from database, Problem is i want to keep the selected value in the dropdown if page reloads. Any help will be really appreciated.
Here is my code
<select name="ans_type" class="select-form " onChange="checkAnswer(this.value)" style="background-color: #fff !important;width:159px!important;">
<option value="" style="color:#000">Select</option>
<?php
$sql = "select * from (table name)";
$res = mysqli_query($dbhandle,$sql);
$numrows = mysqli_num_rows($res);
if($numrows){
while($obj = mysqli_fetch_object($res)){
if($ansTypeId == $obj->id){
echo '<option value="'.$obj->id.'" style="color:#000" selected>'.($obj->ans_type).'</option>';
}
else{
echo '<option value="'.$obj->id.'" style="color:#000">'.($obj->ans_type).'</option>';
}
}
}
?>
</select>
Try below code.
<select name="ans_type" class="select-form " onChange="checkAnswer(this.value)" style="background-color: #fff !important;width:159px!important;">
<option value="" style="color:#000">Select</option>
<?php
$selectStr = '';
$sql = "select * from (table name)";
$res = mysqli_query($dbhandle,$sql);
$numrows = mysqli_num_rows($res);
if($numrows){
while($obj = mysqli_fetch_object($res)){
$selectStr = ($ansTypeId == $obj->id) ? 'selected' : '';
echo '<option value="'.$obj->id.'" style="color:#000" '.$selectStr.'>'.($obj->ans_type).'</option>';
}
}
?>
</select>
Try this
selected = '';
if($ansTypeId == $obj->id){
$selected = "selected='selected'";
}
echo '<option value="'.$obj->id.'" style="color:#000" $selected>'.
($obj->ans_type).'</option>';
I want to presist (=keep values if error on form) my values from a dropdown menu , this is what i started with :
...
$priorities = array('low','normal','high');
...
<select name="priority" id="priority">
<?php
foreach ($priorities as $pro){
echo '<option value="'.$pro.'">'.$pro.'</option>';
}
?>
</select>
It does the job but does not presist.
Now i want to get to something like this :
<select name="priority" id="priority">
<?php
$tel = 0;
foreach ($priorities as $pro){
echo '<option value="'.$tel.'"'.htmlentities('<?php if (isset($_POST[\'priority\']) && (int) $_POST[\'priority\'] === tel) { echo \'selected="selected"\'; } ?>').' >'.$pro.'</option>';
$tel++;
}
?>
</select>
But that of course gives an error.
Anyone has any suggestions thx
Here's how I often implement this:
<select name="priority" id="priority">
<?php
foreach ($priorities as $pro)
{
$selected = (isset($_POST['priorities']) && $pro == $_POST['priority']) ? 'selected' : '';
echo '<option value="' . $pro . '" '.$selected.'>' . $pro . '</option>';
}
?>
</select>
Just thought I'd point out you can actually shorten the ternary here like so
<select name="priority" id="priority">
<?php
foreach ($priorities as $pro)
{
$selected = ($pro == #$_POST['priority']) ? 'selected' : '';
echo '<option value="' . $pro . '" '.$selected.'>' . $pro . '</option>';
}
?>
</select>
Sorry I've got a bit of a thing for creating the shortest code possible :)
Change the second part of the code to:
<select name="priority" id="priority">
<?php
foreach ($priorities as $pro) {
if (isset($_POST['priority']) && $_POST['priority'] == $pro) {
$selected = 'selected="selected"';
}
else {
$selected = null;
}
echo '<option value="'.$pro.'" '.$selected.'>'.$pro.'</option>';
}
?>
</select>
Try this
<select name="priority" id="priority">
<?php
$tel = 0;
foreach ($priorities as $pro){
echo '<option value="'
.$tel
.'"'
.(isset($_POST['priority']) && (int)$_POST['priority'] === $tel)?'selected="selected"':''
.' >'
.$pro
.'</option>';
$tel++;
}
?>
</select>
$priority= array (1=>"low","normal","high");
$select = "<select name=\"priority\"> ;
foreach ($priority as $key => $val) {
$select .= "\t<option val=\"".$key."\"";
if ($val == $yourcheckedvariable) {
$select .= " selected=\"selected\">".$val."</option>\n";
} else {
$select .= ">".$val."</option>\n";
}
}
$select .= "</select>";
echo $select;

I am currently working with a dynamic dropdown menu(dependable select boxes). I am pulling the values straight from MySQL DB(if your curious here is how i have the DB SETUP). I am able to get the values of each table and display them accordingly. The problem I am having is echoing the SELECTED value of each selct box. I have a created JS function that will request postfile.php which will then echo the SELECTED value of each box. I am not getting anything echoed. I have checked with firebug but nothing is being posted.
How can I make this work? or Am I approaching this wrong? or Is there a better way? EXAMPLE

Maybe you would like to use jQuery UI auto-complete. It is easier to use and less code. It has a remote data source also. Try this one, maybe this can solve your problem. http://jqueryui.com/demos/autocomplete/
Add on submit action to the form. In the function use the following:
var Myvar = $('#subc3 :selected').text();
