[Check to see if a field is empty before continuing the script]

I  meat the else event // display error

[Check to see if a field is empty before continuing the script]

This was of course my first attempt but this message displays on the initial loading of the page before the form has been submitted

.

[Check to see if a field is empty before continuing the script]

Now this one is a bit of a shit head. I am using a really comprehensive class i found on on the web for upload / re-size / crop but i want to be able to override it's error handling and i am not good enough to start modifying the code in the class with out fucking it up.

 

Firstly i will show you how i have invoked the class.

					if( isset($_FILES['image'] ) ) {

								//Class includes
								include("../scrips/php/cms/database.insert.class.php");
								include ("../scrips/php/cms/img.upload.resize.crop.class.php.php");


								//----------|Start: upload, resize & save
								$your_image = new _image; 

								//----------| Upload orginal image
								$your_image->uploadTo = 'uploads/';
								$upload = $your_image->upload($_FILES['image']);


								//----------| Resize and upload small thumbnail
								$your_image->newPath = 'thums/';
								$your_image->newWidth = 50;
								$your_image->newHeight = 50;
								$resized = $your_image->resize();



								//----------| Resize and upload medium thumbnail
								$your_image->newPath = 'thums2/';
								$your_image->newWidth = 100;
								$your_image->newHeight = 100;
								$resized = $your_image->resize();
								//----------| Getting the image name to insert into the database futher on in the code
								$name = $resized;
								$img_str = explode("/",$name);
								$final_img_name = $img_str['1'];

								echo "Article has been added!";

								//----------------|end

								//----------------| Start database insert (class manipulation)
								$table = "blog_posts"; 
								$title = "'".$_POST['ArticleTitle']."',"; 
								$img = "'".$final_img_name."',"; 
								$post = "'".$_POST['ArticleBody']."',"; 
								$aurthor_id = "'1',";
								$category_id = "'".$_POST['Category']."',";
								$date_posted = "NOW()";


								$values = array("$title","$img","$post","$aurthor_id","$category_id","$date_posted");
								$fields = array('title,','img,','post,','aurthor_id,','category_id,','date_posted'); 
								$obj= new DatabaseInsert;
								$obj->DatabaseConnectionRequire();
								$obj->ArticleInsert($values,$fields,$table);
								//----------------|end
						}

 

As you can see it's fairly basic. What i want to do is before it runs this script and starts including/invoking the class etc, i want to be able to check to see if there is a value been posted from a FILE FORM OBJECT and if there is to proceed with this script, alternatively i want it to execute another code which will handle it in regards to the concept of my page. A simple javascript alert with be ok providing it reloaded the page to it's default state. If any one can help me here i would appreciate it a lot. Thanks

[PHP & Jquery]

Finaly found a way around it. I guess i should of listend to you in the first place!!

 

Thank you!

[PHP & Jquery]

No this is the problem the logic is in order of which i want it to be becuase of other functionality within the document. This is why i have to result in finding an alt solution.

 

This is the peice of code i need to modify in order to solve this issue. I would prefer a simple echo with jquery/ajax to make a live area.

if(isset($_POST['val'])) {
                        include("../scrips/php/cms/delete.multiple.itmes.php");
                        $table = "blog_posts";
					if(isset($_POST['SelectedItems'])) {

						$ids = $_POST['SelectedItems'];
						$obj= new MultipleDelete;
                       		$obj->delete($ids,$table);
						echo "<script type='text/javascript'>
                               		 $('#CommentBox').fadeIn(2000);
                              	  </script>";
                        	

					}

[PHP & Jquery]

Alright guys, I have a bit of a problem here. I am deleting records using isset($_POST) on the current page but when it submits the records i deleted are still visible. I was thinking of echoing some jquery/ajax to re-load the div that displays the records. Has anyone ever done this before?

 

I dont want the entire page to re-load just that specific area.

[Post back problem]

All i want is a bit of code saying if the page loaded 4 seconds ago re-load this specific div.

[Post back problem]

yes! could you help?

[Reloading problem]

I didnt want to post the code becuase there is quite a lot of it but here it is anyway

 

<?php

if(isset($_GET['id'])) {

$DeleteId = $_GET['id'];

mysql_query("DELETE FROM blog_posts WHERE ID=$DeleteId") or die (mysql_error());

echo "Record #".$DeleteId." had been sucessfully deleted.";

} ?>

 

 

<?php 
				$rowNum = "0";
				while($record_rows = mysql_fetch_array($records_returned)){
					if(++$rowNum % 2 == 1 ) {
			?>
                <form action="" method="post" name="DeleteSelected">
                <div class="Record">
                	<div class="Thumbnail"><img src="../img/articles/thums/<?php echo $record_rows['img_url']; ?>" class="RecordThumbnail"/></div>

[Reloading problem]

Yea i know this, i am just tring to create the primary functions in. The other part of the code is a while loop that creats a list of records, each row containing a button that says delete with the url as...

[Reloading problem]

				if(isset($_GET['id'])) {
					$DeleteId = $_GET['id'];
					mysql_query("DELETE FROM blog_posts WHERE ID=$DeleteId") or die (mysql_error());
					echo "Record #".$DeleteId." had been sucessfully deleted.";
				}

[Reloading problem]

I am delete records using $_POST on the current page using isset() function. The records are deleting and the isset function is working but the corresponding record still appears in the list of records until the page is reloaded again.

[gettting a single value to post from a while loop to delete the corrisponding]

I just tried this approach and it doesnt seem to be working to well for me. This is what i have just done...

 

The link

<a href="?id=<?php echo $record_rows['id']; ?>">delete me</a>

 

Post check

<?php 
if(isset($_POST['id'])) {
      $DeleteId = $_POST['id'];
      echo $DeleteId;
}
?>

[gettting a single value to post from a while loop to delete the corrisponding]

I understand were your comming from but i dont want to submit the id from another page i want it to post to the current page and use isset($_post).

[gettting a single value to post from a while loop to delete the corrisponding]

It's actualy a form button though, can i apple a link to it?

[gettting a single value to post from a while loop to delete the corrisponding]

i have a while loop that builds up a table of records, each row has a button that needs to have an action to delete that specific record. I can think of the obvious way around this and add a form around each row and set the button to type="submit". However there is a problem i have the entire table of records wrapped within in a form object for other functionalities.

 

Does anyone have a solution for this problem?
