PHP, Parse error: syntax error, unexpected T_IF, expecting T_FUNCTION

Question

Parse error: syntax error, unexpected T_IF, expecting T_FUNCTION in C:\wamp\www\Exam Creator\cls_FillInTheBlank.php on line 31

I received this error while trying to run the cls_FillInTheBlank.php which includes cls_template.php. I have the two files posted at the for review.

cls_FillInTheBlank.php

<?php

    include("cls_template.php");

class fillintheblank{

    function _construct(){
        $cls_blankInput = new template;
        $cls_questionString = new template;
        $cls_fillInTheBlank = new template;
    }

    if(class_exists($cls_blankInput)){
        $cls_blankInput->fillString("<input type='text' name='[qInputName]' id='[qInputId]' value='[qInputValue]' />");
        $cls_blankInput->fillPlaceholderStrings(array("[qInputName]","[qInputId]","[qInputValue]"));
    } else {
        print("\$cls_blankInput not defined.<br>");
    }

    if(class_exists($cls_questionString)){
        $cls_questionString->fillString("");    // to be set later
        $cls_questionString->fillPlaceholderStrings(array("[fib_blank]"));
    } else {
        print("\$cls_questionString not defined.<br>");
    }

    if(class_exists($cls_fillInTheBlank)){
        $cls_fillInTheBlank->fillString("<li>[qFillInTheBlankString]</li>");
        $cls_fillInTheBlank->fillPlaceholderStrings(array("[qFillInTheBlankString]"));
    } else {
        print("\$cls_fillInTheBlank not defined.<br>");
    }

Answer 1

You've basically got this:

class fillintheblank {
   if (...) {
   }
   if (...) {
   }
}

That's not permitted. A class definition has member variables and method definitions (ie: functions). You can't put "naked" PHP code in a class definition. YOu'll have to wrap it in a method, probably a constructor.

Answer 2

Your problem is you started a class, but then you started writing what would usually be found in a function body in it. You need to enclose lines 27-56 in a function definition.

Also, unrelatedly, you named a method _construct when you probably meant __construct. Two underscores, not just one.
