To make an WordPress widget I created a select box which gets options generated dynamically from $post object. The select box's name is also generated by dynamically. Here is the code
<select class="widefat" name="<?php echo $this->get_field_name( 'employee' );?>" id="<?php echo $this->get_field_id( 'employee' ); ?>">
Results this :
<select class="widefat" name="widget-employee[13][department]" id="widget-employee-13-department">
To check the value of the select box I need to pass it to $_POST Array.
How do I pass the select box's value to $_POST array ?
Thanks in advance.
On submit, the $_POST variable will contain all the input fields/selected values etc. from your form in it. You don't have to manually add anything. You can manually pull info from your $_POST variable if you wish.
You said you want to check $_POST against your value ($post->post_title), in that case, since your select has a name
widget-employee[13][department]
You'll use something like
$_POST['widget-employee'][13][department]
The best bet is to just use print_r($_POST) to see the contents of your $_POST variable and see what is in it, so that you can check against.

So my code is pretty straightforward. I am just getting a field value from the global fields (Options). So this field is on Dashboard -> Options (I have ACFpro) and I am trying to echo out a logo which is an image array.
This is how my code looks like
<ul class="text-white p-0">
<a class="brand " href="/">
<?php
$image = get_field('logo');
echo '<p id="debug">'.($image ['url']).'</p>';
?>
</a>
</ul>
al i am trying to do is pull the url value and insert it to a <p> tag just to make sure it pulls the right value. but instead I am getting this error.
error when trying to echo $image
Any idea on what am I doing wrong?
It is one of two things. You need to add the ID or options to the get_field() as a parameter or you need to adjust the return format. By default it tries to pull the ID of the page get_field() is on.
I would change it to
get_field( 'logo', 'options' );
Or change options to whatever you called your options page.

Does anyone know how to not clear the form on submit when using WPForms (Wordpress). I have hooked in custom processing on submit and I want to just leave the form up on the page, and ajax process the input, and not clear the form on completion (so the user can submit again easily on any error).
If you are willing to make changes to the code, you could consider returning the input value which has been submitted to be displayed in the input field... I have extracted some code from the woocommerce form-login.php as an example:
<input type="email" class="woocommerce-Input woocommerce-Input--text input-text" name="username" id="username" autocomplete="username" value="<?php echo ( ! empty( $_POST['username'] ) ) ? esc_attr( wp_unslash( $_POST['username'] ) ) : ''; ?>" />
If you input a value for username, hit submit, and the form returns for any reason to that same page, the last entered value would be displayed in that input field.
I am using the theme my login WordPress plugin, using the custom pages I have added my own registration fields and validated them with no issues.
However I have worryingly discovered that corrupt code can be added and update to the profile page once a user is registered, I am wondering if there is the same offering for the profile page in terms of validation as there is for the registration?
The best way would be to use "theme my login" template pages, it already have the registration and profile part. You can add and remove fields to your liking and also style it, here is a tutorial for that
http://www.jfarthing.com/development/theme-my-login/adding-extra-registration-fields/.
If you have your custom built profile page then i suggest you use wpnonce to check the validity of the POST requests. Secondly use wordpress's own functions for fetching and updating data. Functions like get_user_meta and update_user_meta, these come built in with all the validation and you dont have to worry about it.
EDIT : I have written this code to demonstrate how to use a nonce field and then how to check the validity of the nonce field (By default Nonces are valid for 24 hours). The code below adds a form and asks for users height. The first php part wont run until the post request has been made. Once the request has been made then it checks for the integrity of the request. If all conditions are met then it will add a new meta field in the database called 'user_height', and will be updated every time the user changes it. Once the height has been set, it will also auto populate this in the input box, so they can see what is their current height. I hope this code covers all your doubts of showing user meta, adding/updating user meta and also validation nonces.
<?php
// Checking if the post request has been submitted and then verifing nonce
if (!isset( $_POST['get_user_height'] ) || !wp_verify_nonce( $_POST['get_user_height'], 'user_body_built' )
) {
print 'Sorry, the request cannot be verified.';
exit;
} else {
if(isset($_POST['user_height']) && !empty($_POST['user_height'])){
update_user_meta( $user_id, 'user_height', $_POST['user_height']);
}
}
<form method="post">
// Fetching previous height of user
<?php $user_height = get_user_meta($user_id, 'user_height', TRUE);?>
// Getting user's height and then saving it to users meta, if height was already set it will also show the current height.
<input type="text" name="user_height" <?php if($user_height){echo 'value="'.$user_height.'"';} ?> placeholder="enter your height">
// Generating a nonce field which will be checked on post request
<?php wp_nonce_field( 'user_body_built', 'get_user_height' ); ?>
</form>
Second EDIT (showcasing how to use existing registration fields on profile page, replace input names with the ones on registeration page): Just add this code in your profile page or functions.php it will automatically show these fields in the profile page.
function tml_edit_user_profile( $profileuser ) {?>
<p>
<label for="phone_number">Phone Number</label>
<!-- replace name attribute with the ones used on registration page -->
<input id="phone_number" type="text" name="phone_number" value="<?php echo $profileuser->phone_number; ?>" />
</p>
<?php
}
add_action( 'edit_user_profile', 'tml_edit_user_profile' );
Having an issue whereby the checkboxes inside a metabox aren't saving. I can save one value and have it return the value of checked to the checkboxes, just not multiple values, which I need. I've tried adding a foreach loop to the update_post_meta code but it didn't work. Slightly confused as to where I'm going wrong.
checkbox code is:
$areas = $wpdb->get_results("SELECT * FROM locations ORDER BY locationName ASC");
if( count($areas) ) :
?>
<div id="locationAssignedBoxes" size="1">
<?php
foreach($areas as $area) :
?>
<input type="checkbox" id="locationAssigned" name="locationAssigned" value="<?php echo $area->id; ?>"<?php if(get_post_meta($post->ID, 'locationAssigned', true) == $area->id) { ?> checked="checked"<?php } ?> /> <?php echo $area->locationName; ?><br>
<?php
endforeach;
?>
</div>
<?php
endif;
?>
Update_post_meta code is:
update_post_meta($post->ID, 'locationAssigned', $_POST['locationAssigned']);
Thanks very much!
This isn't a cut-and-paste answer to your question, but it should help. (I'm trying to solve a similar problem.)
Your problem in general: update_post_meta() saves a single meta value, not a collection of values. Because you want to save the values of multiple checkboxes, you have two choices:
Call update_post_meta() once for each of the checkboxes, creating a
collection of meta values associated with the post.
Combine all of the checkbox values into a single string and save those as a single value with one update_post_meta() call.
These two earlier questions are related and might point you in the right direction.

I want to attach a file to a post and "do something with it later". The file isn't being pulled over when I publish/update my post, the error I get is an empty filename. If I change the input type to text and submit I can get the text to save/display but trying to upload the file acts as though I haven't supplied the file to the form:
form --
function display_file_upload_meta_box($post_id,$post){
wp_nonce_field( basename( __FILE__ ), 'file_upload_meta_box_nonce' );
?>
<p>
<?php
$fileUpload= get_post_meta($object->ID,'file-upload-meta',true);
if(!$fileUpload)
$fileUpload = '';
echo 'file: '.$fileUpload;
?>
<label for="file_upload_meta">Attach a file to this post</label>
<input type="file" id="file_upload_meta" name="file_upload_meta" class="widefat"/>
</p>
<?php
}
code to upload file --
$new_meta_value = wp_upload_bits($_FILES["file_upload_meta"]['name'], null, file_get_contents($_FILES["file_upload_meta"]['tmp_name']));
It's probably because the form does not have those attributes :
enctype="multipart/form-data" encoding="multipart/form-data"
You can use a hook to add them, check this : https://gist.github.com/rfmeier/3513349
