![]() Note that the code within the if and else cannot both be executed, as the if statement cannot evaluate to both true and false at one time! Here is what would happen if we changed to $number_three to anything besides the number 3. On the other hand, if the if statement was false, then the code contained in the else segment would have been executed. The code contained within the else segment will not used.All code that is contained between the opening curly brace ââ will be executed when the if statement is true. So, how would I go about changing the result based on the outcome of a PHP If statement, like in the login.php file I have below.$number_three is indeed Equal To 3 and so this statement will evaluate to true.To do such a comparison we use â =â, which in English means âIs Equal Toâ. In this example we compared a variable to an integer value.The if statement is used to execute a block of code only if the specified condition evaluates to true. We first made a PHP variable called $number_three and set it equal to 3. Conditionals - PHP Basics The if Statement.I have a function called btnShowNew in and when I click submit button it always. if, if-else, if-elseif-else statements are conditional. This code is untested but should do what you want.This is a lot to digest in one sitting, so let us step through the code, line by line. And If data is unique, I want to insert into the database. We use conditional statements in programming to apply different actions on different conditions. ![]() $post_tag will be empty if there is nothing with this tag, and $post_cat gets what you want. I'm assuming your two $post_cat and $post_tag searches do what you want for these two cases - i.e. What you can do is test have_posts before you start the while loop, and then keep which ever query you want in a new variable. You can't start it inside one if then end it somewhere else (although that would be nice!) If statements contain statements that are only executed when the condition is satisfied. ![]() This means that if you have a form field and it does an if-else statement, it may run. The PHP while command doesn't work like that, it needs to start and end in the same code block. In this tutorial youll learn how to write decision-making code using if.else.elseif statements in PHP. It doesnt know whether the user has entered data and submitted or not. Right now, this means we need to add some if statements to see if the array keys exist, starting with the name: have_posts()) : $catquery->the_post() While($tagquery->have_posts()) : $tagquery->the_post() If there is no ''event' tag, only the recent post of Party category will display Depending on what you wrote for the method in the form and using REQUEST in the php, REQUEST will use Get if GET is written for the method and REQUEST. If the post with category Party has tag which is 'event', it is the one that will display In PHP, there is an alternative syntax for writing if statements when performing conditional execution of code, allowing us to use colon and semi-colon when. When you put a semicolon at the end of a condition, like this: if (choice1 choice2) you are telling. ![]() I want to filter my post based on category (Party) In JavaScript semicolons mark the end of statements.
