Remembering Form Data

Let's set the value of these form fields equal to the user data. 0:00 Currently we are setting the variables for the form fields after the form post. 0:05 That means when we view the form before it's submitted, 0:10 those variables won't exist. 0:13 So we would need to check if those variables are set 0:15 before we could use them in the form value. 0:18 But there's another way. 0:21 Let's set each of these variables to an empty string at the beginning of our 0:22 script, then we know that the variable is set and we can use it even if it's empty. 0:26 We can add each of these on one line, putting them all together. 0:35 $project_id = $title which equals $date which 0:39 equals $time which finally equals our empty string. 0:44 Now let's use the variables to update the form field values. 0:50 As we explored in the previous course, 0:59 it's a good idea to escape output whenever you output user data. 1:01 Be sure to check the notes associated with this video for 1:05 a more detailed explanation. 1:08 We'll use HTML special chars for this. 1:10 So our PHP will echo htmlspecialchars, And our title. 1:15 Then close our php. 1:26 Let's copy that code for $date and $time as well. 1:27 We have to do something a little different for our select. 1:39 After I select value, let's break this up. 1:42 Then we can add a conditional, 1:53 if ($project_id == $item 1:57 Project_id Then 2:02 we're going to echo selected. 2:09 Now let's refresh the browser, resubmitting the form data. 2:16 This time the fields we already filled out are still complete. 2:20 So I can easily choose a project, And submit the form again. 2:24 This time we're redirected to the task list where we see our new task. 2:31
