That will obviously fail, since notice 1# has already told us headerSwap() does not know what $config is.
PHP SWITCH CASE ALL CODE
Finally, we learned how using switch-case can be faster than if-else blocks in certain situations. PHP also supports the alternative syntax for the switch statement as follows: We also saw how to write case statements that cover multiple conditions. For example, in the above structure, the expression is. In respect of the second notice, you are then saying give me the properties ' urls' and ' templates' of this variable $config. In this tutorial, I showed you how to use switch-case statements in PHP in place of if-else blocks to execute code conditionally. PHP switch statement tests the value of an expression against a list of case values successively. Regarding the first notice, this takes us back to what I stated earlier headerSwap() does not know what $config is. Why is this happening? Remember, you are including your *.inc files within the context of a function headerSwap(). The switch-case statement is an alternative to the if-elseif-else statement, which does almost the same thing. If you were testing with Tracy, she would have shown you where the error was, to be precise, these 2 PHP notices. We have 2 great utilities in ProcessWire (besides PHP itself) to help us with these, namely $config->debug = true and Tracy Debugger. Note that on the last link, our Default content will show, since we have not passed the variable. The if statement is also a decision-making statement in PHP and other programming languages. By attaching the variable name 'Content' to our link, we pass that condition in the query string. The switch case is the decision-making statement in PHP. it gives you the ability to show blocks of information 'on the fly'. As you see, the PHP switch statement is popular for its ability to deal with several conditions and select a particular code block to run. I can't stress enough the importance of debugging and testing your code. Case switching is a neat way to make your site a bit more dynamic. It now appears that processwire "cant" access the urls to the stylesheets anymore, and are just coming up as: In my headers, I had a few stylesheets that I was linking via Yes, I know it's a complete mess, but no clue how to do this.Thanks for your help! However, this has caused a new issue. Depending on the value of a specific variable (or 'traffic signal'), the switch statement directs the flow of your code execution through different 'lanes' or cases. I only know the most basic form of switch command, I assume that my code should be something like: $my_text = function_output($product,$type) A PHP switch statement, in its simplest form, is like a traffic cop directing cars at an intersection. Intuitively it sounds like something to handle with switch command, but I really don't know how to use it the way I want, which probably involves a function. If the type is special, no matter what the price is -> Echo It's If price > 0 -> Echo $ sign + the price $productīy default/fallback -> Don't echo anything ( lorem ipsum stuff means I have some static content within the code). My code pattern would be something like: lorem I want to echo a message according to the price, and to the type, for each product. When I break in the switch contect, it seems to break the loop. I also have various "product types", which are manually defined in my code, each with index number that will relate to each product accordingly: $type1="normal" PHP jjshell October 15, 2008, 12:11pm 1 Hello, I’m using a swtich inside a foreach loop. I have various products inside a database, each has its own price, the pattern to output a product price is:PHP SWITCH CASE ALL HOW TO
