below is the code which i have problem and the problem is how can i get values if value="php echo $someting;" instead of value="someting"
like how i put value when i use condition if($_POST['city']=='')
how can i put echo value in if statement
anyone got my point then please answer.
<select class="js-example-placeholder-single js-states form-control" id="city" name="city"
title="Select City" data-hide-disabled="true" data-live-search="true">
<optgroup label="Location">
<option value="">No Selection</option>
<?php
$cities = $db->get ("cities");
foreach ($cities as $city){
?>
<option value="<?php echo $city['city_name']; ?>" <?php if($city['city_name'] ==
$selected_city) echo "selected"; ?> >
<?php echo $city['city_name']; ?>
</option>
<?php } ?>
</optgroup>
</select>
Just add empty($_POST['city']) ? 'selected' : '' on empty option:
<?php
$selected_city = $_POST['city'] ?? null;
?>
<select class="js-example-placeholder-single js-states form-control" id="city" name="city" title="Select City" data-hide-disabled="true" data-live-search="true">
<optgroup label="Location">
<option value="" <?= empty($selected_city) ? 'selected' : ''; ?>>No Selection</option>
<?php
$cities = $db->get("cities");
foreach ($cities as $city):
?>
<option value="<?= $city['city_name']; ?>" <?= $city['city_name'] == $selected_city ? 'selected' : ''; ?>>
<?= $city['city_name']; ?>
</option>
<?php endforeach; ?>
</optgroup>
</select>

Consider:
<form method="get" action="">
<select name="name">
<option value="a">a</option>
<option value="b">b</option>
</select>
<select name="location">
<option value="x">x</option>
<option value="y">y</option>
</select>
<input type="submit" value="Submit" class="submit" />
</form>
On submitting the form, how do I make sure that the selected values remain selected in the dropdowns? This form is inside WordPress (PHP).
To avoid many if-else structures, let JavaScript do the trick automatically:
<select name="name" id="name">
<option value="a">a</option>
<option value="b">b</option>
</select>
<script type="text/javascript">
document.getElementById('name').value = "<?php echo $_GET['name'];?>";
</script>
<select name="location" id="location">
<option value="x">x</option>
<option value="y">y</option>
</select>
<script type="text/javascript">
document.getElementById('location').value = "<?php echo $_GET['location'];?>";
</script>
<select name="name">
<option <?php if ($_GET['name'] == 'a') { ?>selected="true" <?php }; ?>value="a">a</option>
<option <?php if ($_GET['name'] == 'b') { ?>selected="true" <?php }; ?>value="b">b</option>
</select>
After trying all these "solutions", nothing work. I did some research on W3Schools before and remember there was explanation of keeping values about radio.
But it also works for the Select option. See below for an example. Just try it out and play with it.
<?php
$example = $_POST["example"];
?>
<form method="post">
<select name="example">
<option <?php if (isset($example) && $example=="a") echo "selected";?>>a</option>
<option <?php if (isset($example) && $example=="b") echo "selected";?>>b</option>
<option <?php if (isset($example) && $example=="c") echo "selected";?>>c</option>
</select>
<input type="submit" name="submit" value="submit" />
</form>
If you are using WordPress (as is the case with the OP), you can use the selected function.
<form method="get" action="">
<select name="name">
<option value="a" <?php selected( isset($_POST['name']) ? $_POST['name'] : '', 'a' ); ?>>a</option>
<option value="b" <?php selected( isset($_POST['name']) ? $_POST['name'] : '', 'b' ); ?>>b</option>
</select>
<select name="location">
<option value="x" <?php selected( isset($_POST['location']) ? $_POST['location'] : '', 'x' ); ?>>x</option>
<option value="y" <?php selected( isset($_POST['location']) ? $_POST['location'] : '', 'y' ); ?>>y</option>
</select>
<input type="submit" value="Submit" class="submit" />
</form>
Since WordPress already uses jQuery you can try something like this:
var POST=<?php echo json_encode($_POST); ?>;
for(k in POST){
$("#"+k).val(POST[k]);
}
JavaScript only solution:
var tmpParams = decodeURIComponent(window.location.search.substr(1)).split("&");
for (var i = 0; i < tmpParams.length; i++) {
var tmparr = tmpParams[i].split("=");
var tmp = document.getElementsByName(tmparr[0])[0];
if (!!tmp){
document.getElementsByName(tmparr[0])[0].value = tmparr[1];
}
}
Or if you are using jQuery you can replace
var tmp = document.getElementsByName(tmparr[0])[0];
if (!!tmp){
document.getElementsByName(tmparr[0])[0].value = tmparr[1];
}
with:
$('*[name="'+tmparr[0]+'"]').val(tmparr[1]);
Try this solution for keep selected value in dropdown:
<form action="<?php echo get_page_link(); ?>" method="post">
<select name="<?php echo $field_key['key']; ?>" onchange="javascript:
submit()">
<option value="">All Category</option>
<?php
foreach( $field['choices'] as $key => $value ){
if($post_key==$key){ ?>
<option value="<?php echo $key; ?>" selected><?php echo $value; ?></option>
<?php
}else{?>
<option value="<?php echo $key; ?>"><?php echo $value; ?></option>
<?php }
}?>
</select>
</form>
This works for me!
<label for="reason">Reason:</label>
<select name="reason" size="1" id="name" >
<option value="NG" selected="SELECTED"><?php if (!(strcmp("NG", $_POST["reason"]))) {echo "selected=\"selected\"";} ?>Selection a reason below</option>
<option value="General"<?php if (!(strcmp("General", $_POST["reason"]))) {echo "selected=\"selected\"";} ?>>General Question</option>
<option value="Account"<?php if (!(strcmp("Account", $_POST["reason"]))) {echo "selected=\"selected\"";} ?>>Account Question</option>
<option value="Other"<?php if (!(strcmp("Other", $_POST["reason"]))) {echo "selected=\"selected\"";} ?>>Other</option>
</select>
Just change this line:
<input type="submit" value="Submit" class="submit" />
with this line:
<input type="submit" value="Submit/Reload" class="submit" onclick="history.go(-1);">
I don't work in WordPress much, but for forms outside of WordPress, this works well.
PHP
location = ""; // Declare variable
if($_POST) {
if(!$_POST["location"]) {
$error .= "Location is required.<br />"; // If not selected, add string to error message
}else{
$location = $_POST["location"]; // If selected, assign to variable
}
HTML
<select name="location">
<option value="0">Choose...</option>
<option value="1" <?php if (isset($location) && $location == "1") echo "selected" ?>>location 1</option>
<option value="2" <?php if (isset($location) && $location == "2") echo "selected" ?>>location 2</option>
</select>
<select name="name">
<?php $options = ["a", "b", "c", "d", "e"];
foreach($options as $o){
if($o == $_GET['name']) $attr="selected='true'";
else $attr = "";
echo "<option value='{$o}' {$attr}>{$o}</option>";
}
?>
</select>
We can create an array of option before hand and only use simple if/else to check if selected or not. If you want different values for data and different value for displaying option you can use associative arrays too.
<select name="name">
<?php $options = ["a"=>"Option A", "b"=>"Option B", "c"=>"Option C", "d"=>"Option D", "e"=>"Option E"];
foreach($options as $index=>$o){
if($index == $_GET['name']) $attr="selected='true'";
else $attr = "";
echo "<option value='{$index}' {$attr}>{$o}</option>";
}
?>
</select>
<form method="get" action="">
<select name="name" value="<?php echo $_GET['name'];?>">
<option value="a">a</option>
<option value="b">b</option>
</select>
<select name="location" value="<?php echo $_GET['location'];?>">
<option value="x">x</option>
<option value="y">y</option>
</select>
<input type="submit" value="Submit" class="submit" />
</form>
I have a country dropdown
<select name="country" class="form-control"/>
<option>Select a Country</option>
<?php foreach($country_list as $country) :?>
<option value="<?php echo $account_result->Country;?>"
<?php
if($country->id==$account_result->Country)
{echo 'selected="selected"';};?>>
<?php echo $country->name; ?></option>
<?php endforeach; ?>
</select>
but while updating I am getting only selected value id it's not changing.
You setting same value to all options change this line:
<option value="<?php echo $account_result->Country;?>"
to:
<option value="<?php echo $country->id;?>"
Try below
You have added wrong value in option
<select name="country" class="form-control"/>
<option>Select a Country</option>
<?php foreach($country_list as $country) :?>
<option value="<?php echo $country->id;?>"
<?php
if($country->id==$account_result->Country)
{echo 'selected="selected"';};?>>
<?php echo $country->name; ?></option>
<?php endforeach; ?>
</select>
<?php echo $country->id == $account_result->Country ?"selected":"";?>
your $country->id and $account_result->Country should be same value example
ex: 44=44
then it will be get selected in default page load.
and you have to set the option value as like this.
<option value="<?php echo $country->id;?>"
I have an array as follows
$myArray = array('a','b','c','d');
I need to distribute some values of them saved already in database into different number of select boxes let's say 4 list boxes so these saved values will appear selected in the first list boxes and the remaining ones will be default and let's say saved values are a and c
so based on that the output should have 4 list boxes starting with a (Selected) and second list box c (Selected) and the other 2 list boxes should be remained default something like that
<select id="id" name="id" class="form-control">
<option value="">No selection</option>
<option value="a" selected>a</option>
<option value="b">b</option>
<option value="c">c</option>
<option value="d">d</option>
</select>
<select id="id" name="id" class="form-control">
<option value="">No selection</option>
<option value="a">a</option>
<option value="b">b</option>
<option value="c" selected>c</option>
<option value="d">d</option>
</select>
<select id="id" name="id" class="form-control">
<option value="" selected>No selection</option>
<option value="a">a</option>
<option value="b">b</option>
<option value="c">c</option>
<option value="d">d</option>
</select>
<select id="id" name="id" class="form-control">
<option value="" selected>No selection</option>
<option value="a">a</option>
<option value="b">b</option>
<option value="c">c</option>
<option value="d">d</option>
</select>
Edit
Here is my code where i loop to produce either 7 or 9 list boxes according to the passed value and inside i loop on $municipals to show all municipals and a municipal exists inside an array of the saved values in DB i need to show it in the first select box and so on
<?php if(!empty($municipal_number->meta_value)):
$ids = array();
foreach($municipal_ids as $municipal_id) {
$ids[] = $municipal_id->meta_value;
}
if($municipal_number->meta_value == 7):
for ($x = 1; $x <= 7; $x++): ?>
<div class="col-lg-3">
<label>Select Municipal</label>
<select id="municipal_id_<?php echo $x; ?>" name="municipal_id[]" class="municipal_id form-control">
<option value="0" selected>No Municipal</option>
<?php foreach($municipals as $municipal): ?>
<?php if(in_array($municipal->id, $ids)): ?>
<option selected value="<?php echo $municipal->id; ?>"><?php echo $municipal->first_name.' '.$municipal->last_name; ?></option>
<?php else: ?>
<option value="<?php echo $municipal->id; ?>"><?php echo $municipal->first_name.' '.$municipal->last_name; ?></option>
<?php endif; ?>
<?php endforeach; ?>
</select>
</div>
<?php endfor;
elseif($municipal_number->meta_value == 9):
for ($x = 1; $x <= 9; $x++): ?>
<div class="col-lg-3">
<label>Select Municipal</label>
<select id="municipal_id_<?php echo $x; ?>" name="municipal_id[]" class="municipal_id form-control">
<option value="0" selected>No Municipal</option>
<?php foreach($municipals as $municipal): ?>
<?php if(in_array($municipal->id, $ids)): ?>
<option value="<?php echo $municipal->id; ?>"><?php echo $municipal->first_name.' '.$municipal->last_name; ?></option>
<?php else: ?>
<option value="<?php echo $municipal->id; ?>"><?php echo $municipal->first_name.' '.$municipal->last_name; ?></option>
<?php endif; ?>
<?php endforeach; ?>
</select>
</div>
<?php endfor; ?>
<?php endif; ?>
<?php endif; ?>
Make use of array_shift() function and a simple for loop to implement your logic, like this:
$myArray = array('a','c');
for($i = 0; $i < 4; ++$i){
$flag = false;
?>
<select id="id" name="id" class="form-control">
<option value="">No selection</option>
<option value="a" <?php if(!$flag && in_array('a', $myArray)){ echo "selected='selected'"; $flag = true; } ?>>a</option>
<option value="b" <?php if(!$flag && in_array('b', $myArray)){ echo "selected='selected'"; $flag = true; } ?>>b</option>
<option value="c" <?php if(!$flag && in_array('c', $myArray)){ echo "selected='selected'"; $flag = true; } ?>>c</option>
<option value="d" <?php if(!$flag && in_array('d', $myArray)){ echo "selected='selected'"; $flag = true; } ?>>d</option>
</select>
<?php
array_shift($myArray);
}
Note: Take care of id and name attributes, it should be unique for every element.
Here's some sample code:
$myArray = array('a','b','c','d');
$selected_values = array('a','c');
$number_of_selects = 4;
for ($i = 0; $i < $number_of_selects; $i++) {
$sel_val = !empty($selected_values[$i])? $selected_values[$i] : false;?>
<select>
<?php
foreach ($myArray as $v) {?>
<option value="<?=$v?>" <?=$v===$sel_val? 'selected' : ''?>><?=$v?><option>
<?php
}?>
</select>
<?php
}
I want to update my form when I click edit button then all info is showing correctly but status value is showing all time same open option. I dont know why it is showing same open status and my currently status is done but it is showing all time open please help me to fix this issue thanks
this is my form code username is showing correctly but status is not showing correct
<p><label class="field" for="username">UserName:</label>
<input name="username" type="text" id="username" value="<?php echo $username; ?>" size="50" />
</p>
<p>
<label class="field" for="Status">Status</label>
<select name="status" id="status" value="<?php echo $status; ?>" >
<option value="open">Open</option>
<option value="done">Done</option>
<option value="pending">Pending</option>
<option value="working">Working</option>
</select>
</p>
Use selected attribute.
<select name="status" id="status">
<option value="open" <?php if($status=="open") { echo "selected"; } ?> >Open</option>
<option value="done" <?php if($status=="done") { echo "selected"; } ?> >Done</option>
<option value="pending" <?php if($status=="pending") { echo "selected"; } ?> >Pending</option>
<option value="working" <?php if($status=="working") { echo "selected"; } ?> >Working</option>
</select>
This is wrong way, correct way is to use like this,
<select name="status">
<?php
$options = array("open","done","pending","working");
$selected = "done";
foreach($options as $option){
if($selected==$option){
echo '<option value="'.$option.'" selected="selected">'.ucfirst($option).'</option>';
}else{
echo '<option value="'.$option.'">'.ucfirst($option).'</option>';
}
}
?>
</select>
If you really want to embed the status in the options tag, you should use the 'selected' attribute for selection of the tag options. Here is your modified code with correct handling:-
<p><label class="field" for="username">UserName:</label>
<input name="username" type="text" id="username" value="<?php echo $username;?>" size="50" />
</p>
<p>
<label class="field" for="Status">Status</label>
<select name="status" id="status" >
<option value="open" <?php echo $status == 'open' ? 'selected' : ''; ?>>Open</option>
<option value="done" <?php echo $status == 'done' ? 'selected' : '' ;?>>Done</option>
<option value="pending" <?php echo $status == 'pending' ? 'selected' : '' ; ?>>Pending</option>
<option value="working" <?php echo $status == 'working' ? 'selected' : '' ; ?>>Working</option>
</select>
</p>
You need selected tag. Modify your form like this
<select name="status" id="status"> <!-- value removed, there's no use of it here -->
<option value="open" <?php if ($status=="open") {echo "selected"}?>>Open</option>
<option value="done" <?php if ($status=="done") {echo "selected"}?>>Done</option>
....
</select>
Use selected attribute for option.
Change your code as
<select name="status" id="status">
<option value="open" <?php selected($status, 'open'); ?>>Open</option>
<option value="done" <?php selected($status, 'done'); ?>>Done</option>
<option value="pending" <?php selected($status, 'pending'); ?>>Pending</option>
<option value="working" <?php selected($status, 'working'); ?>>Working</option>
</select>
<?php
function selected( $selected_value, $value ) {
if( $selected_value === $value ) {
echo 'selected=true';
}
}
?>
Consider:
<form method="get" action="">
<select name="name">
<option value="a">a</option>
<option value="b">b</option>
</select>
<select name="location">
<option value="x">x</option>
<option value="y">y</option>
</select>
<input type="submit" value="Submit" class="submit" />

</script>
<select name="name">
<option <?php if ($_GET['name'] == 'a') { ?>selected="true" <?php }; ?>value="a">a</option>
<option <?php if ($_GET['name'] == 'b') { ?>selected="true" <?php }; ?>value="b">b</option>
</select>
After trying all these "solutions", nothing work. I did some research on W3Schools before and remember there was explanation of keeping values about radio.
But it also works for the Select option. See below for an example. Just try it out and play with it.
<?php

Since WordPress already uses jQuery you can try something like this:

for(k in POST){
$("#"+k).val(POST[k]);
}
JavaScript only solution:
var tmpParams = decodeURIComponent(window.location.search.substr(1)).split("&");
for (var i = 0; i < tmpParams.length; i++) {
var tmparr = tmpParams[i].split("=");
var tmp = document.getElementsByName(tmparr[0])[0];
if (!!tmp){
document.getElementsByName(tmparr[0])[0].value = tmparr[1];
}
}
Or if you are using jQuery you can replace
var tmp = document.getElementsByName(tmparr[0])[0];
if (!!tmp){
document.getElementsByName(tmparr[0])[0].value = tmparr[1];
}
with:
$('*[name="'+tmparr[0]+'"]').val(tmparr[1]);
Try this solution for keep selected value in dropdown:
<form action="<?php echo get_page_link(); ?>" method="post">
<select name="<?php echo $field_key['key']; ?>" onchange="javascript:
submit()">
<option value="">All Category</option>
<?php
foreach( $field['choices'] as $key => $value ){
if($post_key==$key){ ?>
<option value="<?php echo $key; ?>" selected><?php echo $value; ?></option>
<?php
}else{?>
<option value="<?php echo $key; ?>"><?php echo $value; ?></option>
<?php }
}?>
</select>
</form>
This works for me!
<label for="reason">Reason:</label>
<select name="reason" size="1" id="name" >
<option value="NG" selected="SELECTED"><?php if (!(strcmp("NG", $_POST["reason"]))) {echo "selected=\"selected\"";} ?>Selection a reason below</option>
<option value="General"<?php if (!(strcmp("General", $_POST["reason"]))) {echo "selected=\"selected\"";} ?>>General Question</option>
<option value="Account"<?php if (!(strcmp("Account", $_POST["reason"]))) {echo "selected=\"selected\"";} ?>>Account Question</option>
<option value="Other"<?php if (!(strcmp("Other", $_POST["reason"]))) {echo "selected=\"selected\"";} ?>>Other</option>
</select>

<input type="submit" value="Submit" class="submit" />
with this line:
<input type="submit" value="Submit/Reload" class="submit" onclick="history.go(-1);">
