    GD Library problem

    in PHP Coding Help

    Posted

    the Modify button seems to have vanished from my previous psot so please excuse the doubble post..


    P.S.:

    before the obvious "answers" come in, I have uncommented the line, i have restarted the webserver, there are no extra gd2.dlls, i only have 1 php.ini on my comp, and no gd doesnt show up in phpinfo();, also gd_info is an undefined function. the extension_dir is correct and php_gd2.dll does exist in the extension dir

    hope you can help :(

    GD Library problem

    in PHP Coding Help

    Posted

    I'm having the exact same problem, php_gd2.dll is present in my extension_dir, and i have uncommented ;extension=php_gd2.dll, but gd functions do not work for me..

    Fatal error: Call to undefined function imageCreateFromJpeg() in E:\htdocs\test.php on line 16

    though the code is irrelevant to the problem at hand I'll post the code anyway (it's directly from php.net as a reference to get started learnign gd functions)

    [code]
    <?php
    $src_file = 'source.jpg';
    list($src_w, $src_h, $src_t, $src_a) = getimagesize($src_file);

    $ptr_file = 'pointer.png'; // must have no transparency, but white background
    list($ptr_w, $ptr_h, $ptr_t, $ptr_a) = getimagesize($ptr_file);

    // destination image dimensions:
    $dst_w = 400;
    $dst_h = 200;

    // pointer position:
    $ptr_x = 195;
    $ptr_y = 70;

    $srcImage = imageCreateFromJpeg($src_file) or die ('failed imageCreateFromJpg');
    $dstImage = imageCreateTrueColor($dst_w, $dst_h) or die ('failed imageCreateTrueColor');

    imageCopyResampled($dstImage, $srcImage, 0, 0, 0, 0, $dst_w, $dst_h, $src_w, $src_h) or die ('failed imageCopyResampled');

    $ptrImage = imageCreateFromPng($ptr_file) or die ('failed imageCreateFromPng');

    $ptr_white = imageColorAllocate($ptrImage,255,255,255);
    imageColorTransparent($ptrImage,$ptr_white);

    imageCopyMerge($dstImage, $ptrImage, $ptr_x, $ptr_y, 0, 0, $ptr_w, $ptr_h, 100) or die ('failed imageCopyMerge');

    imageJpeg($dstImage,'',100) or die ('failed imageJpeg');

    imageDestroy($srcImage) or die ('failed imageDestroy(1)');
    imageDestroy($dstImage) or die ('failed imageDestroy(2)');
    imageDestroy($ptrImage) or die ('failed imageDestroy(3)');
    ?>

    mod_layout

    in Apache HTTP Server

    Posted

    Yes im wondering the same thing, I wish to add a footer with google ads to my site, Mod layout looks like it would work and quite simpol, but I'd like to use mod_include which comes with apache 2.2 before compiling and adding a new module.. I have Includes in the options but cant figure out how to force it to put
    <!--#include virtual="/footer.html" -->
    on the bottom of all my pages, some help would be appreciated with mod_include or mod_layout..

    image upload

    it's image upload... why use SQL? you can do that with plain old PhP, easier, quicker, more efficient, less errored...
    try this maybe?

    [code]
    <?php
    function GetFile() {
    $num = 0;
    while(file_exists($num . ".jpg")){
    $num++;
    }
    return $num;
    }
    $num2 = 0;
    $e = "";
    while ($num2 < GetFile()) {
    $e .= "Image number: #$num2<br><a href=$num2.jpg><img src='$num2.jpg' width=180 height=180 title='click for full size'></a><br>";
    $e .= fread(fopen("$num2.txt", "r"), filesize("$num2.txt"));
    $e .= "<br><hr><br>";
    $num2++;
    }

    if(!isset($img_name)) {
    echo "
    <html>
    <head>
    <title>Picture Uploader</title>
    </head>
    <body>

    <hr>

    NOTE: Security is taken very seriously here, it is tight enough to cause one small bug, while filename.jpg and filename.gif are acceptable<br>
    file.name.jpg and file.name.gif are NOT, sorry for the inconvinience.. just deal with it.<br>
    <u>Rules For Uploading</u>:<br>
    <p>

    Sorting Arrays

    in PHP Coding Help

    Posted

    i had to figure out how to sort arrays for my little mmorpg project, so i know where your coming from in the confusion, here's the part of my code that handles the sorting, see if you can learn from it maybe?

    [code]
    while ($sPC < $mPC) {
    $order[$sPC] = read_key("PC", $sPC, "", "users.ini");
    $orderL[$sPC] = read_key("INFO", "level", 0, read_key("PC", $sPC, "", "users.ini") . "MEEP.ini");
    $sPC++;
    }
    array_multisort($order, SORT_NUMERIC, $orderL);
    [/code]


    for further reference:

    Multilingual page problems

    basically youll need to include a file which has an array of the english word into the other language, then split your dialogues into an array on chr(32), after that you only need to use str_replace($words[$num], $lang[$words[$num]]) in a while statement =)

    A search tutorial?

    in PHP Coding Help

    Posted

    just make a lil bool isin() function using mid() to automatically check a passage of text for the queried string, i think PhP migh thave such a function built in, but im not quite sure.. if not, it's quite easy to make and seems to me to be self explanitroy, then jus torganise your database in a numerical fassion and use a little for() { } or while() { } loop to search database 1 entry at a time for if(isin(current_cell, $_GET["query"]))


    hope this helped... works better and much easier with Ini's than SqL Db's i think

    Really? So the second I attempt to connect you somehow manage to download the entire contents of my 250gb hard drive instantly over my 512Kbps/up DSL? Must be magic.

    its not hard to scan an outside comp and know every file name in every directory in a  "Tree" template

    (
    C
    ---Documents and settings
    ------User
    ---------my documents
    ------------my pictures
    ----------------summer vac01.jpg
    ----------------summer vac02.jpg
    ----------------summer vac03.jpg
    )
    etc.. and have a simple text file of everything, 512kb/s could send a little 3-10kb text file pretty instantly.... and it wouldnt increase the size to much to have a desc added..
    (
    ----------------summer vac01.jpg
                              Author: So&So

                              Format: jpeg/Image File
                              etc..
    )

    so yes thats monitorable, also, a miniscule packet sniffer could be upoaded to your comp, which would monitor all data sent on your network, a keylogger to watch what you type on and offline, and of course a little trojan to upload your files slowly over time.. and no, just because these little virants are "viruses" doesnt mean your multitude of scanners will pick them up.

    jsut clarifying things, back on topic now.. XD

    x[) this is why i don't use MySQL, just enumerate file names (0.jpg, 1.jpg, etc), put security on ur uploader so only certain file types are allowed, then enumerate displays with a function (a little while(file_exists("$num.jpg")) { } loop) and bam, you've avoided your problem
