[Resolved] Adding files manually to children post type

[mohammadD]

I have children post type ,it has a file field. i have created a cred form and i have input like below :

 <input type="file" name="msds[]" class="form-control msdsinput"> 

it should be an array of the files. i have also used cred api to get these files at cred_after_save , the code is like this :

		$files = $_FILES['msds'];
		foreach($cmd as $key=>$f )
		{
			$my_post = array(
				'post_title'      => $f,
				'post_content'  => 'cnt ubuntu',
				'post-type'       => 'post',
				'post_status'     => 'publish',
				'comment_status'  => 'closed',
				'ping_status'     => 'closed'

			);

			// Insert the post into the database and get the resulting id back... 
			$child_post_id = wp_insert_post( $my_post, $wp_error=true );
			set_post_type( $child_post_id, 'inq-cmd' );
				if(isset($files))
				{
				$upload= wp_upload_bits($files["name"][$key], null, file_get_contents($files["tmp_name"][$key]));
				$url=$upload['url'];
				update_post_meta($child_post_id,'wpcf-msds',$url);
				 }
			}
			update_post_meta($child_post_id,
							 '_wpcf_belongs_' . $form_data['post_type'] . '_id',
							 $post_id);
		}
 

it works when i just send a single file ( it's a bit slow though) . but it doesn't work when i use multiple files.
the form is in :
hidden link
i wanted to know is there a better way to handle uploading files with cred ? how should i update file field that i have created with types.
Wish to hear from you soon

Hi, can you provide the full hook code? Some critical information here is missing. The API name "cred_after_save" doesn't exist, and I need to know what $cmd represents here,:

foreach($cmd as $key=>$f )

In the new post arguments, this should be "post_type", not "post-type". You can set inq-cmd as the post type right here:

$my_post = array(
        'post_title'      => $f,
        'post_content'  => 'cnt ubuntu',
        'post_type'       => 'inq-cmd',
        'post_status'     => 'publish',
        'comment_status'  => 'closed',
        'ping_status'     => 'closed'
 
    );

Then you can delete this line, since it's not needed:

set_post_type( $child_post_id, 'inq-cmd' );

Thanks for the post type part , i will use that , if you want to know the whole API part it's like below :

add_action('cred_save_data', 'update_step',10,2);
function update_step($post_id, $form_data)
{
	// if a specific form
	if ($form_data['id']==13865)
	{
		if (isset($_POST['container']) && !isset($_POST['isLCL']))
		{	
			$fields = $_POST['container'];
			$quantity= $_POST['quantity'];
			$gross=$_POST['gross'];
			foreach($fields as $key=>$f )
			{
				$my_post = array(
					'post_title'      => 'cnt'+$key,
					'post_content'  => 'cnt ubuntu',
					'post-type'       => 'post',
					'post_status'     => 'publish',
					'comment_status'  => 'closed',
					'ping_status'     => 'closed'

				);

				// Insert the post into the database and get the resulting id back... 
				$child_post_id = wp_insert_post( $my_post, $wp_error=true );
				set_post_type( $child_post_id, 'inq-cnt' );
				update_post_meta($child_post_id, 'wpcf-inq-cnt-container-size', $f);
				update_post_meta($child_post_id, 'wpcf-inq-cnt-quantity', $quantity[$key]);
				update_post_meta($child_post_id, 'wpcf-inq-cnt-gross-weight', $gross[$key]);
				update_post_meta($child_post_id,
								 '_wpcf_belongs_' . $form_data['post_type'] . '_id',
								 $post_id);
			}

		}
		$cmd = $_POST['cmdname'];
		$hs= $_POST['cmdhs'];
		$dng=$_POST['inq-dng'];
		$files = $_FILES['msds'];
		foreach($cmd as $key=>$f )
		{
			$my_post = array(
				'post_title'      => $f,
				'post_content'  => 'cnt ubuntu',
				'post-type'       => 'post',
				'post_status'     => 'publish',
				'comment_status'  => 'closed',
				'ping_status'     => 'closed'

			);

			// Insert the post into the database and get the resulting id back... 
			$child_post_id = wp_insert_post( $my_post, $wp_error=true );
			set_post_type( $child_post_id, 'inq-cmd' );
			update_post_meta($child_post_id, 'wpcf-commodity-name', $f);
			update_post_meta($child_post_id, 'wpcf-commodity-hs-code', $hs[$key]);
			if($dng[$key]==1||$dng[$key]=='1')
			{
				update_post_meta($child_post_id, 'wpcf-inquiry-dangerous', $dng[$key]);
				if(isset($files))
				{
				$upload= wp_upload_bits($files["name"][$key], null, file_get_contents($files["tmp_name"][$key]));
				/*$attachment_id = media_handle_upload( $files[$key], 0);*/
				$url=$upload['url'];
				update_post_meta($child_post_id,'wpcf-msds',$url);
				 }
			}
			update_post_meta($child_post_id,
							 '_wpcf_belongs_' . $form_data['post_type'] . '_id',
							 $post_id);
		}
		// add it to saved post meta
		add_post_meta($post_id,'wpcf-total-price',0);
	}
}

and if you want to have the form it's like below :

I am sure you may not need them all but i have given you all of them ,if it's a bit confusing feel free to ask and i am sorry for bad coding .
Thanks in advance

[Christian Cox]

Please add some log statements to the hook here:

 if(isset($files))
        {
error_log('----- files ----------');
error_log(print_r($files, true));
        $upload= wp_upload_bits($files["name"][$key], null, file_get_contents($files["tmp_name"][$key]));
        $url=$upload['url'];
        update_post_meta($child_post_id,'wpcf-msds',$url);
         }

Then turn on server logs. If you're not familiar with your environment's server logs, I can show you how to enable them temporarily. Go in your wp-config.php file and look for define(‘WP_DEBUG’, false);. Change it to:

define('WP_DEBUG', true);

Then add these lines, just before it says 'stop editing here':

ini_set('log_errors',TRUE);
ini_set('error_reporting', E_ALL);
ini_set('error_log', dirname(__FILE__) . '/error_log.txt');

Try to submit the form again - once with only one file, and once with multiple files. This should create an error_log.txt file in your site's root directory. Please send me its contents. Once that is done, you can revert the changes you made to wp-config.php.

I think it works fine but check it any way , it had some issued with speed , should i delete temp files ? if yes how .

[Christian Cox]

i wanted to know is there a better way to handle uploading files with cred ? how should i update file field that i have created with types.
Can you explain why is this file input field is necessary? Why not use a Types repeating "file" custom field?

it works when i just send a single file ( it's a bit slow though) . but it doesn't work when i use multiple files.
Check out the WordPress documentation for update_post_meta:
https://codex.wordpress.org/Function_Reference/update_post_meta

update_post_meta( $post_id, $meta_key, $meta_value, $prev_value );

The last parameter, $prev_value, is important when you're dealing with repeating fields. If multiple values exist for this field, and you do not include the 4th parameter when you call update_post_meta, all the values will be overwritten with the same new value. So in the Create New CRED form, you can call add_post_meta instead to be sure all the values are added correctly. Then when you submit the Edit CRED form, you have to be careful that you are updating only one value each time...or you can delete all the old values and add all the values again using add_post_meta.

So can you explain what does not work, exactly?
- Are any files uploaded to the uploads directory? Which ones?
- Are any server-side errors thrown?
- Are any postmeta values added to the child post? What value or values?

[mohammadD]

I needed that because i should have created a file for each child, but repeating field is suggesting multiple files for a same child. and i wanted to create childeren after the parent form were submitted.
Your help in understanding the file structure and input were outstanding , i will use your advice on repeating fields later in my projects.
With thanks and regards
