I am using session storage with drop down list, I need to get retrieve session values on drop down list. I have given below to follow my code. Please help me anyone
<td align="left" width="50%" valign="top" class="bordeau2">
<select name="numFormCand" id="numFormCand" class="saisie" tabindex="1" value="<?php echo $_SESSION['numFormCand'];?>" autofocus >
<option value="-1" >Choisissez</option>
<option id="" value="apple" title="apple">apple</option>
<option id="numFormCand" value="orange">orange</option>
</select>
Use the selected html attribute : https://www.w3schools.com/tags/att_option_selected.asp
<select name="numFormCand" id="numFormCand" class="saisie" tabindex="1" autofocus >
<option value="-1">Choisissez</option>
<option id="" value="apple" title="apple"<?php if ($_SESSION['numFormCand'] == 'apple') { echo ' selected="selected"'; } ?>>apple</option>
<option id="numFormCand" value="orange"<?php if ($_SESSION['numFormCand'] == 'orange') { echo ' selected="selected"'; } ?>>orange</option>
</select>
<?php
session_start();
?>
<select id="session_list" class="session_list">
<?php
if ($_SESSION) {
foreach ($_SESSION as $session_id => $session_value) {
echo '<option value="' . $session_id . '">' . $session_value . '</option>';
}
} else {
echo '<option></option>';
}
?>
</select>

Is there any way to set the selected item in a drop down box using the following 'type' code?
<select selected="<?php print($row[month]); ?>"><option value="Janurary">January</option><option value="February">February</option><option value="March">March</option><option value="April">April</option></select>
The database holds a month.. and I want to allow on the edit page, them to choose this month.. but it to be pre-filled with their current setting?
You need to set the selected attribute of the correct option tag:
<option value="January" selected="selected">January</option>
Your PHP would look something like this:
<option value="January"<?=$row['month'] == 'January' ? ' selected="selected"' : '';?>>January</option>
I usually find it neater to create an array of values and loop through that to create a dropdown.
You mark the selected item on the <option> tag, not the <select> tag.
So your code should read something like this:
<select>
<option value="January"<?php if ($row[month] == 'January') echo ' selected="selected"'; ?>>January</option>
<option value="February"<?php if ($row[month] == 'February') echo ' selected="selected"'; ?>>February</option>
...
...
<option value="December"<?php if ($row[month] == 'December') echo ' selected="selected"'; ?>>December</option>
</select>
You can make this less repetitive by putting all the month names in an array and using a basic foreach over them.
You can use this method if you use a MySQL database:
include('sql_connect.php');
$result = mysql_query("SELECT * FROM users WHERE `id`!='".$user_id."'");
while ($row = mysql_fetch_array($result))
{
if ($_GET['to'] == $row['id'])
{
$selected = 'selected="selected"';
}
else
{
$selected = '';
}
echo('<option value="'.$row['id'].' '.$selected.'">'.$row['username'].' ('.$row['fname'].' '.substr($row['lname'],0,1).'.)</option>');
}
mysql_close($con);
It will compare if the user in $_GET['to'] is the same as $row['id'] in table, if yes, the $selected will be created. This was for a private messaging system...
Simple and easy to understand example by using ternary operators to set selected value in php
<?php $plan = array('1' => 'Green','2'=>'Red' ); ?>
<select class="form-control" title="Choose Plan">
<?php foreach ($plan as $id=> $value) { ?>
<option value="<?php echo $id;?>" <?php echo ($id== '2') ? ' selected="selected"' : '';?>><?php echo $value;?></option>
<?php } ?>
</select>
Its too old but I have to add my way as well :) because it is generic and useful especially when you are using static dropdown values.
function selectdCheck($value1,$value2)
{
if ($value1 == $value2)
{
echo 'selected="selected"';
} else
{
echo '';
}
return;
}
and in you dropdown options you can use this function like this and you can use this as many as you can because it fits with all of your select boxes/dropdowns
<option <?php selectdCheck($row[month],january); ?> value="january">january</option>
:) I hope this function help others
Simple way
<select class ="dropdownstyle" name="category" selected="<?php print($messageeditdetails[0]['category_id']); ?>">
<option value=""><?php echo "Select"; ?></option>
<?php foreach ($dropdowndetails as $dropdowndetails) { ?>
<option <?php if($messageeditdetails[0]['category_id'] == $dropdowndetails['id']) { ?> selected="<?php echo $dropdowndetails['id']; ?>" <?php } ?> value="<?php echo $dropdowndetails['id']; ?>"><?php echo $dropdowndetails['category_name']; ?></option>
<?php } ?>
</select>
This is the solution that I came up with...
<form method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">
<select name="select_month">
<?php
if (isset($_POST['select_month'])) {
if($_POST["select_month"] == "January"){
echo '<option value="January" selected="selected">January</option><option value="February">February</option>';
}
elseif($_POST["select_month"] == "February"){
echo '<option value="January">January</option><option value="February" selected="selected">February</option>';
}
}
else{
echo '<option value="January">January</option><option value="February">February</option>';
}
?>
</select>
<input name="submit_button" type="submit" value="Search Month">
</form>
A Simple Solution:
It work's for me
<div class="form-group">
<label for="mcategory">Select Category</label>
<select class="form-control" id="mcategory" name="mcategory" required>
<option value="">Please select category</option>
<?php foreach ($result_cat as $result): ?>
<option value="<?php echo $result['name'];?>"<?php
if($result['name']==$mcategory){
echo 'selected';
} ?>><?php echo $result['name']; ?></option>
}
<?php endforeach; ?>
</select>
</div>
Check this:
<select class="form-control" id="department" name="department" type="text">
<option value="medical-furniture" #if($list->department == "medical-furniture") selected #endif>Medical furniture</option>
<option value="medical-table" #if($list->department == "medical-table") selected #endif>Medical table</option>
<option value="service" #if($list->department == "service") selected #endif>Service</option>
</select>
My suggestion is to leverage the hidden/collapse attribute. Try with this example:
<select>
<option value="echo $row[month]" selected disabled hidden><? echo $row[month] ?></option>
<option value="1">Jan</option>
<option value="2">Feb</option>
<option value="3">Mar</option>
</select>
in case of null for $row[month] the selected item is blank and with data, it would contain less codes for many options and always working for HTML5 and bootstrap etc...
If you have a big drop down. it's much easier to use jQuery with PHP.
This is how to do it:
<script>
$(document).ready(function () {
$('select[name="country"]').val('<?=$data[0]['Country']?>');
});
</script>
The easiest solution for the selected option in dropdown using PHP is following
<select class="form-control" name="currency_selling" required >
<option value="">Select Currency</option>
<option value="pkr" <?=$selected_currency == 'pkr' ? ' selected="selected"' : '';?> >PKR</option>
<option value="dollar" <?=$selected_currency == 'dollar' ? ' selected="selected"' : '';?> >USD</option>
<option value="pounds" <?=$selected_currency == 'pounds' ? ' selected="selected"' : '';?> >POUNDS</option>
<option value="dirham" <?=$selected_currency == 'dirham' ? ' selected="selected"' : '';?> >DRHM</option>
</select>
You can try this after select tag:
<option value="yes" selected>yes</option>
<option value="no">no</option>
I have some options to select and would like to set some textinputs to visible or hidden depending on what user selects. I have the functionality already but in this case I need to take the second value of the echo and check if its equal to something, I can currently only check the first value of the echo:
<select id="type_id" name="device_type_id" onchange="if (this.value==''){this.form['device_imei_textinput'].style.visibility='hidden'}else{this.form['device_imei_textinput'].style.visibility='visible'};">
<option value='Select'>Select</option>
<?php foreach ($result as $row) { ?>
<option value="<?php echo $row['id'] . $row['serial_or_imei'] ?>"> <?php echo $row['name']; ?> </option>;
<?php } ?>
</select>
So, I need to get ONLY the value of $row['serial_or_imei'] and compare onchange="if (this.value=='') , how can I do that?
EDIT: further explanation
I need to read the value of $row['serial_or_imei'] which could be empty, 'serial' OR 'imei', so, one of these three.
P.S: I must keep the $row['id'] in the value attribute because I am passing that value later to server so dont suggest removing that.
You can add one attribute to option element and test with it. something like
<select id="type_id" name="device_type_id" onchange="if (this.getAttribute('data')==''){this.form['device_imei_textinput'].style.visibility='hidden'}else{this.form['device_imei_textinput'].style.visibility='visible'};">
<option value='Select'>Select</option>
<?php foreach ($result as $row) { ?>
<option data="<?php echo $row['serial_or_imei'] ?>" value="<?php echo $row['id'] . $row['serial_or_imei'] ?>"> <?php echo $row['name']; ?> </option>;
<?php } ?>
</select>
You can compare the value of an array in the onchange by assign the value to a variable which will be a quite neat format as
<?php $value = echo $row['serial_or_imei']; ?>
<select id="type_id" name="device_type_id" onchange="if (this.value=='<?php empty($value)?>'){this.form['device_imei_textinput'].style.visibility='hidden'}else{this.form['device_imei_textinput'].style.visibility='visible'};">
<option value='Select'>Select</option>
<?php foreach ($result as $row) { ?>
<option value="<?php echo $row['id'] . $row['serial_or_imei'] ?>"> <?php echo $row['name']; ?> </option>;
<?php } ?>
</select>
You add a new custom attribute serial and supply the value of serial_or_imei to it and then compare in javascript with onchange="if (this.value=='')
<select id="type_id" name="device_type_id" onchange="if (this.value==''){this.form['device_imei_textinput'].style.visibility='hidden'}else{this.form['device_imei_textinput'].style.visibility='visible'};">
<option value='Select'>Select</option>
<?php foreach ($result as $row) { ?>
<option value="<?php echo $row['id'] . $row['serial_or_imei'] ?>" data-serial="<?php echo $row['serial_or_imei'] ?>"> <?php echo $row['name']; ?> </option>;
<?php } ?>
</select>
EDIT: Attribute “serial” is not allowed on element “option”. Changed this to data-seial.
You say you need the values back to server because they change dynamically. A clean way would be to have a dedicated hidden field:
<?php foreach ($result as $row) { ?>
<input type="hidden" name="map[<?php echo $row['id']; ?>]" value="<?php echo $row['serial_or_imei']; ?>">
<? } ?>
Here's a full self-contained script to illustrate it:
<?php
$random_serial_or_imei = range(1000, 9999);
shuffle($random_serial_or_imei);
$result = [];
for ($i = 0; $i < 5; $i++) {
$result[] = [
'id' => $i,
'serial_or_imei' => $random_serial_or_imei[$i],
'name' => "Name #$i",
];
}
?>
<select name="device_type_id">
<option value="">Select</option>
<?php foreach ($result as $row) { ?>
<option value="<?php echo $row['id']?>"><?php echo $row['name']; ?></option>
<?php } ?>
</select>
<?php foreach ($result as $row) { ?>
<input type="hidden" name="map[<?php echo $row['id']; ?>]" value="<?php echo $row['serial_or_imei']; ?>">
<? } ?>
This prints something like:
<select name="device_type_id">
<option value="">Select</option>
<option value="0">Name #0</option>
<option value="1">Name #1</option>
<option value="2">Name #2</option>
<option value="3">Name #3</option>
<option value="4">Name #4</option>
</select>
<input type="hidden" name="map[0]" value="9513">
<input type="hidden" name="map[1]" value="3931">
<input type="hidden" name="map[2]" value="3971">
<input type="hidden" name="map[3]" value="4476">
<input type="hidden" name="map[4]" value="6429">
Selected type can be found at $_POST['device_type_id'] and the corresponding IMEI at $_POST['map'][ $_POST['device_type_id'] ].
Based on the information from the comments, I think this solution is what you are looking for. Note I move the onchange to a function for clarity.
You can see the "three" option hides the text input as it doesn't have a imei.
Also notice how I use the data- attribute inside your option so you can retrieve that information as well, independent of the option id. Also note the this.form['device_imei_textinput'] didn't worked. The elements reference is required.
function check_imei(obj, form) {
var imei = obj.options[obj.selectedIndex].getAttribute('data-imei');
if (imei == '') {
form.elements.device_imei_textinput.style.visibility='hidden';
} else {
form.elements.device_imei_textinput.style.visibility='visible';
}
}
<form>
<select id="type_id" name="device_type_id" onchange="check_imei(this, this.form);">
<option value='Select'>Select</option>
<option value="1" data-imei="foo">One</option>
<option value="2" data-imei="bar">Two</option>
<option value="3" data-imei="">Three</option>
</select>
<input type="text" id="device_imei_textinput" name="device_imei_textinput" />
</form>
Mirror of example : https://jsfiddle.net/asp1hewx/
EDIT : To address the PHP side of things, the form above could be generated with :
<form>
<select id="type_id" name="device_type_id" onchange="check_imei(this, this.form);">
<option value='Select'>Select</option>
<?php foreach ($result as $row) { ?>
<option value="<?php echo $row['id'] . $row['serial_or_imei'] ?>" data-imei="<?php $row['serial_or_imei'] ?>"><?php echo $row['name'] ?></option>
<?php } ?>
</select>
<input type="text" id="device_imei_textinput" name="device_imei_textinput" />
</form>
Hi i am storing countries and states in database i need to edit and update it in database but when i click on edit option iam not able to fetch the record from database.Here is my code.

Country:<select name="country" class="countries" id="country" value="<?php echo $row['country'];?>">
<option >Select Country</option>
</select><br/>
State:<select name="state" class="states" id="state" value="<?php echo $row['state'];?>">

If i click on console the value is printing but iam not able to display in frontend.Can anyone help me regarding this.
please use this code.
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<script src="http://lab.iamrohit.in/js/location.js"></script>

<option >Select State</option>
</select><br/>
There were few things which were wrong.
Option should be inside select box
select value should be based on database condition
Thanks
Amit
Select box don't contain value attribute. You are going by wrong way.
You can use select box by this way:-
<select name="country">
<option value="country1" <?php if ($row['country'] == 'country1') { echo ' selected="selected"'; } ?>>country1</option>
<option value="country2" <?php if ($row['country'] == 'country2') { echo ' selected="selected"'; } ?>>country2</option>
<option value="country3" <?php if ($row['country'] == 'country3') { echo ' selected="selected"'; } ?>>country3</option>
</select>
<select name="state">
<option value="state1" <?php if ($row['state'] == 'state1') { echo ' selected="selected"'; } ?>>state1</option>
<option value="state2" <?php if ($row['state'] == 'state2') { echo ' selected="selected"'; } ?>>state2</option>
<option value="state3" <?php if ($row['state'] == 'state3') { echo ' selected="selected"'; } ?>>state3</option>
</select>
Hope it will help you :)
You can't assign value attribute to Select Box.So you can use Like this:
<select name="country">
<option value="country" <?php if ($row['country'] == 'country') { echo ' selected="selected"'; } ?>>country</option>
<select name="state">
<option value="state12" <?php if ($row['state'] == 'state12') { echo ' selected="selected"'; } ?>>state12</option>
I have an HTML form that a user can use to edit a row in a mysql database, the PHP script queries the database and then displays the current data in form. I have this working fine for text fields with something like:
Correct Answer:<input type="text" name="answer" value="<?php echo $row['CorrectAnswer']; ?>"><br>
and simple radio set up like:
<?php
if ($row['Hazardous'] == "no"){
?>
Hazardous?:<input type="radio" name="hazardous" value="yes">Yes
<input type="radio" name="hazardous" value="no" checked="checked">No<br>
<?php
}else{
?>
Hazardous?:<input type="radio" name="hazardous" value="yes" checked="checked">Yes
<input type="radio" name="hazardous" value="no" >No<br>
<?php } ?>
I also have a select option element like below:
Category: <select name="category">
<option value="hazardawareness">Hazard Awareness</option>
<option value="observation">Observation</option>
<option value="insurance">Insurance</option>
<option value="attitude">Attitude</option>
<option value="knowledge">Gen. Knowledge</option>
</select><br>
Which im trying to set up, I could use:
<?php if ($row['Category'] == "hazardawareness"){ ?>
Category: <select name="category">
<option value="hazardawareness" selected="selected">Hazard Awareness</option>
<option value="observation">Observation</option>
<option value="insurance">Insurance</option>
<option value="attitude">Attitude</option>
<option value="knowledge">Gen. Knowledge</option>
</select><br>
<?php }else if ($row['Category'] == "observation"){ ?>
Category: <select name="category">
<option value="hazardawareness">Hazard Awareness</option>
<option value="observation" selected="selected">Observation</option>
<option value="insurance">Insurance</option>
<option value="attitude">Attitude</option>
<option value="knowledge">Gen. Knowledge</option>
</select><br>
<?php }else if ($row['Category'] == "insurance"){ ?>
Category: <select name="category">
<option value="hazardawareness">Hazard Awareness</option>
<option value="observation">Observation</option>
<option value="insurance"selected="selected">Insurance</option>
<option value="attitude">Attitude</option>
<option value="knowledge">Gen. Knowledge</option>
</select><br>
<?php }else if ($row['Category'] == "attitude"){ ?>
Category: <select name="category">
<option value="hazardawareness">Hazard Awareness</option>
<option value="observation">Observation</option>
<option value="insurance">Insurance</option>
<option value="attitude" selected="selected">Attitude</option>
<option value="knowledge">Gen. Knowledge</option>
</select><br>
<?php }else if ($row['Category'] == "knowledge"){ ?>
Category: <select name="category">
<option value="hazardawareness" >Hazard Awareness</option>
<option value="observation">Observation</option>
<option value="insurance">Insurance</option>
<option value="attitude">Attitude</option>
<option value="knowledge" selected="selected">Gen. Knowledge</option>
</select><br>
<?php } ?>
But perhaps there is a better method to do this without duplicating so much code?
You can add an if clause on your option creation that will at the selected attribute if needed.
<?php $options = array(
"Hazard Awareness" => hazardawareness,
"Observation" => observation,
"Insurance" => insurance,
"Attitude" => attitude
); ?>
<select name="category">
<?php foreach($options as $display => $value) { ?>
<option value='<?= $value ?>' <?php if($row['Category'] == trim($value)) { ?>selected='selected'<?php } ?>>
<?= $display ?>
</option>
<?php } ?>
</select>
I think this will help you to do the work using less code:
<?php
$options = array(
"Hazard Awareness" => hazardawareness,
"Observation" => observation,
"Insurance" => insurance,
"Attitude" => attitude
);
echo 'Category: <select name="category">';
foreach($options as $display => $value) {
if ($row['Category'] == trim($value)) {
echo '<option value="' . $value . '" selected>' . $display .'</option>';
}
else {
echo '<option value="' . $value . '">' . $display . '</option>';
}
}
echo '</select>';
Put your option data in array().
I have got the following form:
<form action="" method="get" target="_self">
<select name="Category" class="dropmenu" id="Category"onchange="this.form.submit()">
<option value="">Any</option>
<option value="Keyboard"<?php if ($_GET['Category']=="Keyboard") {echo "selected='selected'"; } ?>>Keyboard</option>
<option value="Piano"<?php if ($_GET['Category']=="Piano") {echo "selected='selected'"; } ?>>Piano</option>
</select>
<select name='Manufacturer' class="dropmenu" onChange="this.form.submit()" >
<?php
echo '<option value="">Any</option>';
while ($row = mysql_fetch_array($RS_Search1)) {
$selected = $_GET['Manufacturer'] == $row['Manufacturer'] ? 'selected' : '';
echo '<option '.$selected.'>' . $row['Manufacturer'] . '</option>';
} ?> </select>
<select name="Color" class="dropmenu" onChange="this.form.submit()">
<?php
echo '<option value="">Any</option>';
while ($Color = mysql_fetch_array($RS_Search2)) {
$selected2 = $_GET['Color'] == $Color['Color'] ? 'selected' : '';
echo '<option '.$selected2.'>' . $Color['Color'] . '</option>';
} ?> </form>
Second form to submit
<form action="search2.php" method="get"> </select><input name="Category" type="hidden" value="<?php echo $_GET['Category']; ?>">
<input name="Manufacturer" type="hidden" value="<?php echo $_GET['Manufacturer']; ?>">
<input name="Color" type="hidden" value="<?php echo $_GET['Color']; ?>">
<select name="price" class="dropmenu">
<?php
echo '<option value="">Any</option>';
while ($Price = mysql_fetch_array($RS_Price)) {
$selected3 = $_GET['price_range'] == $Price['price_range'] ? 'selected' : '';
echo '<option '.$selected3.'>' . $Price['price_range']. '</option>';
} ?>
</select><input name="Search2" type="submit" id="Search2" value="Submit">
</form>
As you can see the option values are pulled from a db, after the first value is chosen. What the form does at the minute is reload the whole page. Is there a way to just reload the form in stead of reloading the whole page. I need to keep the values that are submitted on change of a option value to be able to fill in the next drop down menu.
Any help welcome.
