Podcast Do polyglots have an edge when it comes to mastering programming Featured on Meta. For phpBB3, we intend to use a higher level of run-time error reporting. This will mean that the use of an uninitialized variable will be reported as a warning. These warnings can be avoided by using the built-in isset function to check whether a variable has been set - but preferably the variable is always existing.
For checking if an array has a key set this can come in handy though, examples:. The empty function is useful if you want to check if a variable is not set or being empty an empty string, 0 as an integer or string, NULL, false, an empty array or a variable declared, but without a value in a class. An example:. Even if the break for the default case is not needed, it is sometimes better to include it just for readability and completeness.
SQL Statements are often unreadable without some formatting, since they tend to be big at times. Though the formatting of sql statements adds a lot to the readability of code. SQL statements should be formatted in the following way, basically writing keywords:. Use double quotes where applicable. The variables in these examples are typecasted to integers beforehand. In other words use single quotes where no variable substitution is required or where the variable involved shouldn't appear within double quotes.
Otherwise use double quotes. You basically pass the query, the total number of lines to retrieve and the offset. This function already escapes strings and checks other types, so there is no need to do this here. An example of an insert statement would be:.
A typical example of doing a positive match against a number of values would be:. This needs to be used to make sure the resulting statement is working on all supported db's.
Instead of explaining every possible combination, I will give a short example:. As you can see, the logic is pretty self-explaining. Always try to optimize your loops if operations are going on at the comparing part, since this part is executed every time the loop is parsed through. For assignments a descriptive name should be chosen. For little checks it is not noticeable, but if checked against a huge array within a loop those checks alone can take several seconds.
If you need this functionality, try using isset on the arrays keys instead, actually shifting the values into keys and vice versa. For sensitive operations always let the user confirm the action. This makes sure the path is always correct and users being able to just rename the admin folder and the acp still working as intended though some links will fail and the code need to be slightly adjusted.
Some of these functions are only chosen over others because of personal preference and have no benefit other than maintaining consistency throughout the code. That call is necessary because it provides a method for external applications embedding phpBB to be called at the end of the script. Style cfg files are simple name-value lists with the information necessary for installing a style.
Similar cfg files exist for templates, themes and imagesets. These follow the same principle and will not be introduced individually. The important part of the style configuration file is assigning an unique name. Templates should be produced in a consistent manner. Where appropriate they should be based off an existing copy, e. Please also note that the indentation and coding guidelines also apply to templates where possible.
The same applies to most other tags for which additional parameters can be set, consistency is the major aim here. Each block level element should be indented by one tab, same for tabular elements, e.
This applies not to div elements of course. Similarly don't use span at all if another element can contain the class definition, e. Try to match text class types with existing useage, e. Remember block level ordering is important Use a standard cellpadding of 2 and cellspacing of 0 on outer tables. Inner tables can vary from 0 to 3 or even 4 depending on the need. Try to retain consistency of basic layout and class useage, i. Try to keep template conditional and other statements tabbed in line with the block to which they refer.
Firstly templates now take the suffix ". This was done simply to make the lives of some people easier wrt syntax highlighting, etc. This should reduce the need to assign loads of new language variables in MODifications. A bit later loops will be explained further. To not irritate you we will explain conditionals as well as other statements first. Something that existed in 2. This was used for example to output the jumpbox.
This takes the simple form:. You will note in the 3. Note that you can introduce new templates i. No need to modify loads of files as with 2. Added in 3. A contentious decision has seen the ability to include PHP within the template introduced.
This is achieved by enclosing the PHP within relevant tags:. A note, it is very much encouraged that template designers do not include PHP. The ability to include raw PHP was introduced primarily to allow end users to include banner code, etc.
It was not intended for general use Most often, the header and footer are the areas that people want to modify. Editing your footer in phpBB is quite easy when you know how, as the program has integrated a file editor. Below are the steps for modifyingy our footer in phpBB 3. This brings you to the Templates tab. Look under the Installed Templates and find your current template.
In our example, it is the prosilver template. Look to the middle column and click on the Edit link. After you upload the desired image in the imageset folder you can select it from the Image drop-down menu of the same Edit imageset page in the administration panel. From the same page you can also change the images for things other than the logo e. When you're done configuring the settings click on the Submit button at the bottom of the page to save the changes.
After that you can refresh the frontend of your forum to view the results; you might need to purge the phpBB3 cache. In our example we removed the default prosilver style logo:. You can also remove the logo by commenting out the corresponding code directly in the overall-header. The code that needs to be commented out looks like this might be slightly different, depending on the style :.
To comment it out means to put an exclamation mark and two hyphens after the first bracket e. So the above code should look like this when it's commented out:. The overall-header.
