Thanks!

I'm not entirely sure what you want your code to do. Could you describe, in one or two sentences, what you want to print?
-
You'd have to search for if there's a standard way of vendors for formatting the data, that would dramatically speed up the process. Otherwise, you'll have to anticipate for all the variety that's out there.
-
And if you want to be absolutely sure that your code is used, but never more than once at a time, use include_once().

@haku That's strange, I've tried: function confirmation() { var answer = confirm("Are you sure you want to delete the advert?") if (!answer){ return FALSE; } } ...yet if I say no (cancel), the browser still opens to the href path.

Well, back to the drawing board with new lessons learned, and some questions on your mind to guide you, then. We all have to do that.

@Greenwood: Well if you put it like that, I suppose your class has the advantage of getting the data you want in a format that you need and can work with. Didn't mean to diss you, Greenwood. I respect the way you managed to recreate the mysql queries by making easy-to-read method call chains. Well, I do know that it takes a lot of time to get how a class works if that class is too 'intelligent'. Does the difficulty of Unit-Testing increase more with the number of private classes, with the size of the methods, or generally with the degree of autonomy of a class? Yes, I believe that's the way to go. Actually, shouldn't Greenwood's class be regarded as an abstract class? Just to satisfy my curiosity: what kind of applications require domain-related classes to format the query results? Could you give me some hyperlinks?

How can I enter an array into a foreach loop and return it?
Bodhi Gump replied to naike's topic in PHP Coding Help
I believe the array_map function is what you are looking for. -
So you want to copy tables from other sites to put them on your own?
-
Can you be more specific? Please show us your code. Generally you can reuse functions and classes.

Fatal error: DB Error: extension not found
Bodhi Gump replied to chintansshah's topic in Other Libraries
I assume it works from the browser? The php.ini for the browser may include the extension you need, but not the php.ini for the command line. -

How to: make an advanced search template with smarty.
Bodhi Gump replied to klaasvaak's topic in Other Libraries
Smarty is especially made to make the life of web designers easier, I wouldn't recommend it for searching. It's best to do the search server side. Where do you have the data stored? Assuming you have the data on a database, it's just a matter of passing the search paramaters to create a SELECT query. If you have the information elsewhere, for example, inside some specific directory, you can use the function fopen('path/to/file.txt'). -

The href is always called after the onclick function ends. Try this. <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title></title> <script type="text/javascript"> <!-- function confirmation() { var answer = confirm("Are you sure you want to delete the advert?") if (answer){ document.myform.submit(); } } //--> </script> </head> <body> <form name="myform" action="sandbox.php"></form> <button onclick="javascript:confirmation();">CLICK ME</button> </body> </html>

Generating hierarchical categories based on product row
Bodhi Gump replied to quasiman's topic in PHP Coding Help
For each category column $i in the original table: - Get the distinct names. If $i isn't the first column, remember the name of each column's parent column at $i-1; - If $i is not the first column: get the name-id pairs using the parent column names from the previous step; - Insert the distinct names into the new table, giving parent_id=0 for the first $i, and giving the parent_id of their parent column for other $i. If you have columns of the same name at the same level, you'll get into trouble. Other than that, this algorithm should work. -
1) I see that stuff from $results go into variables like $Name in the function LoadUser. What happens to these variables after the function returns $results? 2) What happens to the array that LoadUser returns? 3) Go and google about PHP Arrays and how String indexes work in Arrays.

I see what's going on. Change the query string to: $sql="INSERT INTO $tbl_name(`vecka`, `dag`, `lunch1`, `lunch2`)VALUES('".$_POST['vecka']."','".$_POST['dag']."','".$_POST['lunch1']."','".$_POST['lunch2']."')"; Take good look at the quotes ` and '.

PHP Send Mail Error with Multi-Line Messages
Bodhi Gump replied to mwtillman's topic in PHP Coding Help
Please show the browser output, if you add: var_dump("From: ".$name." <".$email.">\r\n" ."Reply-To: ".$email."\r\n" ."X-Mailer: PHP/" . phpversion()); and var_dump('From: '.$name.' <'.$email.'>'."\r\n" .'Reply-To: '.$email."\r\n" .'X-Mailer: PHP/' . phpversion()); (Use single quotes in the last example.) -
How do you connect with your database? Can you show us the code of that?
-
Hi Greenwood, My first impression? A lot of public methods, and very few private methods. It seems like you're not sure yet to what purpose you built this class and made it so that it can theoretically handle anything. This makes it very flexible, but you have to ask yourself why you would want to use this class over the standard php methods. Relying too much on public methods means that the object has to rely on other objects, which means that when you have to debug a problem related to this object, you have to consider more interactions between objects than is necessary for the task that needs to be done. A general rule of thumb with object oriented programming, is that you want to make the interactions BETWEEN classes as simple as possible, making sure that other classes don't need to know in detail how the classes they interact with achieve their results. What is 'as simple as possible'? Well, you may anticipate that you have to get records from the same joined tables over and over again in different parts of your application. Then it would make your life easier if all that is needed is a call such as get_user_logins($user_id) that either returns an array of records of user login information, or false on error. You don't want to worry about the connection with the database or the table names if at that part of your code, all you need is the login information of some user. If you then get an array of records belonging to the user you specified, splendid! Then you don't have to worry about the internals of your querying mechanics. If you get 'false', then you DO have to worry about that. The bottom line is, that you have to keep in mind how you want to interact with your class (and how NOT to), so that your debugging time decreases because you know which class is supposed to do what, and your method calls are simple and direct. Hope this helps.
