PLEASE!! I'm going mad!! what is the probably very simple solution to my code???

[AliceIsMyName]

Arrgghhhh!!! after hours and hours of twisting my code in all directions I think I need help before I completely ruin my code or even my mind!!

I am a complete novice in php so I hope the answer will stand out to you more experienced coders :S

 

I have been coding a captcha for a form, got that working (after hours and hours, days in fact) which felt really great, but my joy did not last long... What I thought would be easy peasy compared to what I had just coded, is just not working!!!

 

I want the code to return an error message in the case that the captcha entered by the user doesn't match... I have been trying to make at least one of 2 existing strings change to show this message.

 

These strings variables are :

- $captcha_txt (found on index_bis.php lines 27, 45, 49, 61)

- $commentbox_title (found on index_bis.php line90 and on comment_form_with_captcha.php line39)

 

 

This is my first post ever on these so very very useful forums full of talented helpful people! I think I'll celebrate with some chocolate, get over my frustration and wait and pray someone amazing will post an answer back to me soon

This is the url to my little site I'm coding = http://alcox.monline.dk/php2/index_bis.php

The codes are viewable there too since this is part of an assignment for school,  I had to provide links for the teachers

although there is no link there to my comment_form_with_captcha.php source, since it will replace my_comment_form.php once all is working

 

HERE is my code:

 

1 - comment_form_with_captcha.php :

 

<?php 





$a =$_SESSION["captcha"] ;
$b =$_POST["captcha"] ;	


if(! isset($_POST['updated'])){
    $comment_form_html .= show_comment_form_admin(); }



if(isset($_POST["captcha"])) 
if($a==$b){
    $comment_form_html .= update_comment_form();
$commentbox_title .= "Thank you for commenting!"; 
 $commentbox_title_style .=("commentbox_title_thx");
    $comment_form_html .= show_comment_form_admin();}


if(isset($_POST["captcha"])) 
if($a!=$b){
$comment_form_html .= show_comment_form_admin();
$captcha_txt .= "<p class='formtext'>brrrrrrrrrrrrrrrrrrrrrr</p>";}




function show_comment_form_admin(){
    //read data and set user name and comment
$_SESSION['captcha'] = $captcha_input2;
    $comment_form_r = get_comment_form_data();
    $comment = $comment_form_r["p"];
    $usersname = $comment_form_r["h5"];
$directory = 'images/captcha/';
$captcha_imgs = array('4dfoe.jpg', '95f2d.jpg','443ee.jpg', 'ba902.jpg', 'd10fc.jpg','dq7mtl.jpg', 'znmzgn.jpg');
shuffle($captcha_imgs);
foreach ($captcha_imgs as $captcha_img_src);
$captcha_img .= '<img src="images/captcha/' . $captcha_img_src . '"  id="captcha_img" alt="captcha" />'; 
    $captcha_input2 .= str_replace (".jpg","","$captcha_img_src"); 
$captcha_input3 .= '<p>' . $captcha_input2 . '</p>';
$captcha_txt = '<p class="formtext">check that you are human and copy this code:</p>';	
if(isset($_POST["captcha"])) 
if($a!=$b){
$comment_form_html .= show_comment_form_admin();
$captcha_txt .= "<p class='formtext'>brrrrrrrrrrrrrrrrrrrrrr</p>";}

    
    $out = '
    <form method="post" action="#painting_title">
        <fieldset>
        <p class="formtext">Your name:</p>
        <input type="text" name="h5"></input>
        
        <p class="formtext">Your comment:</p>
        <textarea name="p" id="users_comment" rows="" cols=""></textarea>
        
        ' . $captcha_txt . '

        </fieldset>
    </form>
    ';	
    return $out;
}


  




function update_comment_form(){
$img = $_GET['pic'];
     $title = str_replace(".jpg","_", $img);
    $title2 = str_replace("big_","", $title);
    $path = "comment_form.xml";
    $path2 = ($title2) . "comment_data.xml";
$file = "comment_data/".($path);
$file2 = "comment_data/".($path2);
    $xml = simplexml_load_file($file);    
    $usersname = $_POST['h5'];
    $comment = $_POST['p'];
    $xml -> p = '"'. $comment . '"';
    $xml -> h5 = $usersname .=":";
    file_put_contents(($file2), $xml->asXML(), FILE_APPEND);
}

// get_comment_form_data here
function get_comment_form_data(){
$img = $_GET['pic'];
     $title = str_replace(".jpg","_", $img);
    $title2 = str_replace("big_","", $title);
    $path = "comment_form.xml";
    $path2 = ($title2) . "comment_data.xml";
$file = "comment_data/".($path);
$file2 = "comment_data/".($path2);
    $xml = simplexml_load_file($file);
    $comment_form_r = array();
    $comment_form_r["h5"] = $xml -> h5;
    $comment_form_r["p"] = $xml -> p;
    return $comment_form_r;
}


   
    $comments_on_panting =  'comment_data/' . $title2 . 'comment_data.xml';
$comment = file_get_contents($comments_on_panting);


    
    
?>
