How to dropdown to meta box and save data in meta data in db wp?

I create a custom post type of name courses. For this custom post type create a dynamic dropdown meta box data is shown in dropdown but not save in db.Please check my code where i am doing wrong to save data .My meta box is showing up fine, but the data I enter is not saving. I.e. when I click 'update' on the post the meta box reverts back to my placeholder text.

}
}

New solution, as of WP 3.7: save_post_{$post_type}
add_action( 'save_post_my_post_type', 'wpse63478_save' );
function wpse63478_save() {
//save stuff
}

Campaign Monitor Ajax form submission

Campaign Monitor seems to have updated their code snippets to use a different method of submitting the forms. Now in the <form> tag there's a data-id attribute. None of the usual ways of submitting the forms using Ajax work anymore. Does anybody know how to use Ajax to submit the new style of Campaign Monitor forms?
Here's the code snippet Campaign Monitor gives me:
<form id="subForm" class="js-cm-form" action="https://www.createsend.com/t/subscribeerror?description=" method="post" data-id="A61C50BDC994654B1D79D5719EC1255C09788D1CED7F46D508DAE8944C2CB34BA5EC78954EB81FB5F54AD0716B1F245E696D5CFAF72B819D19DC3B44517">
<p>
<label for="fieldEmail">Email</label>
<br />
<input id="fieldEmail" name="cm-wmpt-wmpt" type="email" class="js-cm-email-input"
required />
</p>
<p>
<button class="js-cm-submit-button" type="submit">Subscribe</button>
</p>
</form>
<script type="text/javascript" src="https://js.createsend1.com/javascript/copypastesubscribeformlogic.js"></script>

I emailed their support, so I can answer the question myself. They've replaced all the old methods with their API. You need to have the form's action set to your own endpoint (e.g. signup.php).
I'm using PHP, so I downloaded their PHP API wrapper from https://github.com/campaignmonitor/createsend-php. A simple example is like this:
require_once 'lib/campaignmonitor/csrest_subscribers.php';
$auth = array(
'api_key' => 'Your API key'
);
$wrap = new CS_REST_Subscribers( 'Your list ID', $auth );
$result = $wrap->add( array(
'EmailAddress' => 'Subscriber email',
'Name' => 'Subscriber name',
'CustomFields' => array(
array(
'Key' => 'Field 1 Key',
'Value' => 'Field Value'
),
array(
'Key' => 'Field 2 Key',
'Value' => 'Field Value'
),
array(
'Key' => 'Multi Option Field 1',
'Value' => 'Option 1'
),
array(
'Key' => 'Multi Option Field 1',
'Value' => 'Option 2'
)
),
'ConsentToTrack' => 'yes',
'Resubscribe' => true
) );
Update: Here's my complete PHP if you're curious:
require_once 'libs/campaignmonitor/csrest_subscribers.php';
$success_message = 'You\'ve been signed up for our email list.';
$error_message_general = 'There was a problem signing you up for the email list. Please try again.';
$error_message_format = 'Please enter a valid email address.';
if ( $_SERVER[ 'REQUEST_METHOD' ] !== 'POST' ) {
renderResponse( true, $error_message_general );
}
else {
$api_key = 'your_api_key_here';
$list_id = 'your_list_id_here';
$email = array_key_exists( 'email', $_POST ) ? $_POST[ 'email' ] : '';
$email = cleanInput( $email );
if ( filter_var( $email, FILTER_VALIDATE_EMAIL ) ) {
try {
$auth = array(
'api_key' => $api_key
);
$wrap = new CS_REST_Subscribers( $list_id, $auth );
$result = $wrap->add( array(
'EmailAddress' => $email,
'ConsentToTrack' => 'yes',
'Resubscribe' => true
) );
if ( $result->was_successful() )
renderResponse( false, $success_message );
else
renderResponse( true, $error_message_general );
}
catch ( Exception $e ) {
renderResponse( true, $error_message_general );
}
}
else {
renderResponse( true, $error_message_format );
}
}
function renderResponse( $error, $message ) {
header( 'Content-Type: application/json' );
$result = [
'error' => $error,
'message' => $message
];
echo json_encode( $result );
die();
}
function cleanInput( $data ) {
$data = trim( $data );
$data = stripslashes( $data );
$data = htmlspecialchars( $data );
return $data;
}

King Composer - add multiple JS file for Google Map Field

I need to add multiple JS file in using king composer.
I follow Add Map
but could not load multiple files.
Code is use for WordPress theme option for show map on selection page.
<?php
$kc->add_map(array(
'location' => array(
'name' => 'Locations',
'description' => 'Add your location details',
'icon' => 'cpicon kc-icon-map',
'category' => 'Content',
'assets' => array(
'scripts' => array(
'googlemap_js' => "MY JS FILE PATH",
'type' => 'javascript',
'jquery' => '',
) ,
'scripts' => array(
'location_js' => 'MY JS FILE PATH',
'type' => 'javascript',
'jquery' => '',
) ,
) ,
'params' => array(
array(
'name' => 'image',
'label' => 'Upload Images',
'type' => 'attach_images',
'admin_label' => true,
) ,
)
) ,
));
?>

You are using wrong ways to add the scripts;
It must be
<?php
$kc->add_map(array(
'location' => array(
'name' => 'Locations',
'description' => 'Add your location details',
'icon' => 'cpicon kc-icon-map',
'category' => 'Content',
'assets' => array(
'scripts' => array(
'googlemap_js' => "MY JS FILE PATH",
'location_js' => 'MY JS FILE PATH',
'js_lib1' => 'MY JS FILE PATH',
'js_lib2' => 'MY JS FILE PATH',
'jquery' => '', //calling the script enqueue before - enqueue from other place.
) ,
) ,
'params' => array(
array(
'name' => 'image',
'label' => 'Upload Images',
'type' => 'attach_images',
'admin_label' => true,
) ,
)
) ,
));
?>

Dropdown javascript onload

I have a dropdown menu, that has a onchange function. Once the function is executed it changes another dropdown menu.
I need to make it so it executes the script onload.
1st dropdown:
echo $form->field($model, 'company_id')->dropDownList($items_company, ['prompt' => 'Select Company', 'style' => 'width:400px;', 'onchange' => '
$.post("index.php?r=project/lists&id=' . '"+$(this).val(), function( data ) {
$( "select#project-client" ).html( data );
console.log("On change");
console.log(data);
});
',])->label('Company');
2nd dropdown:
echo '<label class="control-label">Company Client</label>';
echo Select2::widget([
'model' => $model,
'attribute' => 'client',
'theme' => Select2::THEME_BOOTSTRAP,
'options' => [ 'label' => 'Client',
'multiple' => true, 'style' => 'width:400px;', 'overwriteInitial' => true],
'pluginOptions' => [
'disabled' => false,
],
]);
This is what I tried:
$(document).ready(function () {
var currentProjectCompany = $('#project-company_id').val();
$.post("index.php?r=project/lists&id=' . '" + currentProjectCompany, function (data) {
$("select#project-client").html(data);
console.log("Company ID:");
console.log(currentProjectCompany);
console.log("Clients");
console.log(data);
});
});

Move the onchange code into its own function (it should be there anyway), and execute that function in the ready() function.
That way it will fire both onchange and onload.

I do the same check my code it may help you .But i use ajax and jquery.
For firs dropdown .
echo $form->dropDownListGroup(
$model 'id', array(
'wrapperHtmlOptions' => array(),
'widgetOptions' => array(
'data' => abc::getName($model->id),
'htmlOptions' => array(
'prompt' => 'Select Project',
'ajax' => array(
'type' => 'POST',
'url' => ( Yii::app()->createUrl('/' . $domain_name . '/qq/xyz/abc') ),
'update' => '#seconddropdownid',
//'dataType' => 'json',
'data'=>array('id'=>'js:this.value'),
)
),
),
)
);
in second dropdown :
echo $form->dropDownListGroup(
$project, 'tag', array(
'wrapperHtmlOptions' => array(),
'widgetOptions' => array(
'data' =>$this->getProjectTags(),
'htmlOptions' => array(
'prompt' => 'Select Tags',
),
)
)
);
on change of the second list you can update the the list-view of yii .

How to combine the functionality of a list with a textbox

Right now I have a form that I created in cakephp and it works fine but the problem I am running into is that we run queries off of the type in the database and there have been some user errors with spelling so I would like to have a list with the most common types that you can select from but if it is not in the list you can still type in something different.
I found this jquery autocomplete combobox that works great but I am not able to enter something that is not in the list. http://jqueryui.com/autocomplete/#combobox
I don't know if you need to see my form or not but I will post it anyway
<?php
echo $this->Form->create( 'Credential', array( 'class' => 'popup_form' ) );
echo $this->Form->hidden( 'account_id', array( 'value' => $account_id ) );
echo $this->Form->hidden( 'user_id', array( 'value' => $currentUser['User']['id'] ) );
echo $this->Form->hidden( 'created', array( 'value' => date("Y-m-d H:i:s") ) );
echo $this->Form->hidden( 'modified', array( 'value' => date("Y-m-d H:i:s") ) );
echo '<br/><br/>';
echo $this->Form->input( 'type', array( 'div' => false, 'label' => false, 'placeholder' => 'Account Type' ) );
echo '<br/><br/>';
echo $this->Form->input( 'url', array( 'div' => false, 'label' => false, 'placeholder' => 'URL' ) );
echo '<br/><br/>';
echo $this->Form->input( 'username', array( 'div' => false, 'label' => false, 'placeholder' => 'Username' ) );
echo '<br/><br/>';
echo $this->Form->input( 'password', array( 'div' => false, 'label' => false, 'placeholder' => 'Password' ) );
echo '<br/><br/>';
echo $this->Js->submit( 'Create Credential', array( 'div' => false, 'class' => 'button white medium', 'before' => 'return submitForm();', 'success' => "$('#qtip-add_account_credential').hide();", 'complete' => 'loadTasks();' ) );
echo '<br/><br/>';
echo $this->Form->end();
?>
<script type="text/javascript">
function submitForm(){
var x = document.getElementById("CredentialType").value;
if (x == null || x == "") {
alert("Account Type must be filled out");
return false;
}
else {
return true;
}
}
</script>
I am a backend developer and would love any help I could get on the front end. Thanks.

What you are searching for is a datalist (new in HTML5):
http://www.w3schools.com/tags/tag_datalist.asp
It provides an form input with a predefined list of options, which appears as soon as the user's input matches one of the entries.
BUT: it seems not to be supported in Safari
In your case it would look like that:
<input name="type" list="AccountTypes" placeholder="Account Type">
<datalist id="AccountTypes">
<option value="admin">
<option value="user">
<option value="something else">
</datalist>
