Question

I have created a form online and when the user clicks submit I want the form to check for error (ie missing field). At the moment I have the form checking the fields one by one and as soon as it encounters a error it will exit without checking the rest of the fields. Is there any way I can combine all the if statements that check for errors into one.

Here is the code

 //Code to check that the Student Name field is completed
    if(empty($_POST['studentName'])) 
    {
    $studentNameError = "You did not enter the student name Wank";
    //echo "<h3> $studentNameError </h3>";
    exit();
    }
    //Code to check that the Tutor Name field is completed
    if(empty($_POST['tutorName'] ))
    {
    echo "<h3>You did not select a tutor name. Please go back and select your name from the tutors list</h3>";
    exit();
    }
    //Code to check that the Procedure field is completed
    if(empty($_POST['procedure'] ))
    {
    echo  "<h3>You did not select a procedure. Please go back and enter the name of the procedure which you undertook</h3>";
    exit();
    }
    //Code to check that the Grade field is completed
    if(empty($_POST['grade'] ))
    {
    echo "<h3>You did not select a grade. Please go back and select your grade from the drop down list</h3>";
    exit();
    }
    //Code to check that the Student Reflection field is completed
    if(empty($_POST['studentReflection'] ))
    {
    echo "<h3>The student did not enter any comments for this procedure. Student reflection is required for each procedure. Please go back and enter any comments</h3>";
    exit();
    }
    //Code to check if the tick box is checked that the tutor comment is entered

    if( !strlen($_POST['tutorComments']) && isset($_POST['alert'] ))
    {
        echo "<h3>You must enter a reason why you have clicked the alert box</h3>";
        exit();
    }

For example, you can make a boolean variable to mark, if there is an error, and exit if it’s true + combine error messages into one

$error = false;
if(empty($_POST['studentName'])) 
{
$errorMessages[] = "You did not enter the student name Wank";
$error = true;
}
//Code to check that the Tutor Name field is completed
if(empty($_POST['tutorName'] ))
{
$errorMessages[] = "You did not select a tutor name. Please go back and select your name from the tutors list";
$error = true;
}
//Code to check that the Procedure field is completed
if(empty($_POST['procedure'] ))
{
$errorMessages[] = "You did not select a procedure. Please go back and enter the name of the      procedure which you undertook";
$error = true;
}
//Code to check that the Grade field is completed
if(empty($_POST['grade'] ))
{
$errorMessages[] ="You did not select a grade. Please go back and select your grade from the drop down list";
$error = true;
}
//Code to check that the Student Reflection field is completed
if(empty($_POST['studentReflection'] ))
{
$errorMessages[] = "The student did not enter any comments for this procedure. Student reflection is required for each procedure. Please go back and enter any comments";
$error = true;
}
//Code to check if the tick box is checked that the tutor comment is entered

if( !strlen($_POST['tutorComments']) && isset($_POST['alert'] ))
{
    $errorMessages[] = "You must enter a reason why you have clicked the alert box";
    $error = true;
}
if($error)
{
    echo("<h3>".implode('<br/>',$errorMessages)."</h3>");
    exit();
}
