PHP - Creating Images

This is so hard. :/

I have the following code:

Code: [Select]
<?php
$signature = @imagecreate(350,60);
$image_generate = imagecolorallocate($signature,84, 84, 84);
$red = imagecolorallocate($signature,255,36,0);

imagefilledrectangle($signature, 0, 1, 150, 30, $red);

header("Content-type:image/png");
imagepng($signature);


?>

How can I get the rectangle in the center?

I don't really know what to change to get it in the right coordinates. :/

I have this script from http://lampload.com/...,view.download/ (I am not using a database) I can upload images fine, I can view files, but I want to delete them. When I press the delete button, nothing happens   http://www.jayg.co.u...oad_gallery.php   <form> <?php $dir = dirname(__FILENAME__)."/images/gallery" ; $files1 = scandir($dir); foreach($files1 as $file){ if(strlen($file) >=3){ $foil = strstr($file, 'jpg'); // As of PHP 5.3.0 $foil = $file; $pos = strpos($file, 'css'); if ($foil==true){ echo '<input type="checkbox" name="filenames[]" value="'.$foil.'" />'; echo "<img width='130' height='38' src='images/gallery/$file' /><br/>"; // for live host //echo "<img width='130' height='38' src='/ABOOK/SORTING/gallery-dynamic/images/gallery/ $file' /><br/>"; } } }?> <input type="submit" name="mysubmit2" value="Delete"> </form>   any ideas please?   thanks

Hello everyone,

I found a tutorial on creating a pdf with php and I just tried to create a basic pdf to see if it worked and modify it from there.  Here is the link to the tutorial: http://www.astahost.com/info/tfclt-create-pdf-php-create-fly-pdf-web-server.html

Well, after uploading the following php file to the server and testing it, I got this error:

Fatal error: Call to undefined function pdf_new() in /home/caresa6/public_html/BubblyBounce.com/admin/pdftest.php on line 2

Here's the code that produced the error:
Code: [Select]
<?php
$mypdf = PDF_new();
PDF_open_file($mypdf, "");
PDF_begin_page($mypdf, 595, 842);
$myfont = PDF_findfont($mypdf, "Times-Roman", "host", 0);
PDF_setfont($mypdf, $myfont, 10);
PDF_show_xy($mypdf, "Sample PDF, constructed by PHP in real-time.", 50, 750);
PDF_show_xy($mypdf, "Made with the PDF libraries for PHP.", 50, 730);
PDF_end_page($mypdf);
PDF_close($mypdf);

$mybuf = PDF_get_buffer($mypdf);
$mylen = strlen($mybuf);
header("Content-type: application/pdf");
header("Content-Length: $mylen");
header("Content-Disposition: inline; filename=gen01.pdf");
print $mybuf;

PDF_delete($mypdf);
?>

Can anyone help me figure out what to do from here?  I have some PHP knowledge, but I'm treading in uncharted waters with this, so I am totally lost.  Thanks in advance.

Hi,

I have decided to try and write some OO php.

I have a simple class with one function. I am trying to instantiate an object of that class using the new operator but get an error.
Parse error: syntax error, unexpected T_OBJECT_OPERATOR in C:\wamp\www\School\addcourse.php on line 38
Code: [Select]

<?php 
    $CDBController = new CMasterDataController; //THIS IS LINE 38
    CMasterDataController->PerformQuery("SOME SQL HERE");
?>

I am including the file that contains this class (CMasterDataController) in this file (addcourse.php). The version of PHP i am using is 5.3.8.
Does anybody know what I am missing?

Thanks,
Joe

Write a  class for feeding a horse. The Horse object should keep track of the last time it was fed and calculate when it is hungry. Assume there is another class that checks the horse every 10 minutes to see if it is hungry and if it is, it calls another method which feeds it. There should be about 3 methods on the class, but more can be added if needed. 

Hi,

I'm developing an iPhone app that's going to need data from a MySQL database, it's just a simple list of my bands upcoming gigs.

So I understand that I need to build an API - I've found some scripts here and there, I just need some advice as to 'what' I should build...JSON? XML? something else?

I don't know anything about it and cant really find anything that will tell me.

Hopefully, If I can get a good method going I will be able to use it for various other app ideas.


Any suggestions are greatly appreciated.

Can anyone guide me on how to create thumbnails with php/gd. I'm trying to use gd to create thumbnails and then store in in my server. I'm currently using a function in my script, but some thumbnails come out black.

elseif ($extension == "gif") $originalImage = ImageCreateFromGIF($sourceImagePath);
elseif ($extension == "png") $originalImage = ImageCreateFromPNG($sourceImagePath);
elseif($extension == "bmp") $originalImage = ImageCreateFromWBMP($sourceImagePath);  // removed since Windows BMP is not supported
$newImage = ImageCreateTrueColor($new_x, $new_y);
ImageCopyResampled($newImage, $originalImage, 0, 0, $srcx, $srcy, $new_x, $new_y, $srcw, $srch);

Hello every body. Currently I am creating a quiz section but I'm facing some problem.   The thing i want is that the questions which the user has played before should not come again.   So here is my quiz table.

+-------------+-------------------------------------+------+-----+---------+----------------+
| Field       | Type                                | Null | Key | Default | Extra          |
+-------------+-------------------------------------+------+-----+---------+----------------+
| qid         | int(11)                             | NO   | PRI | NULL    | auto_increment |
| questions   | varchar(255)                        | NO   | UNI | NULL    |                |
| correct_ans | varchar(50)                         | NO   |     | NULL    |                |
| option1     | varchar(50)                         | NO   |     | NULL    |                |
| option2     | varchar(50)                         | NO   |     | NULL    |                |
| option3     | varchar(50)                         | NO   |     | NULL    |                |
| category    | enum('Maths','Bollywood','Special') | NO   |     | NULL    |                |
+-------------+-------------------------------------+------+-----+---------+----------------+

Then I have created another tablle where I stored their user id and the questions Iid they have played. Here is the table.

+----------------+---------+------+-----+---------+-------+
| Field          | Type    | Null | Key | Default | Extra |
+----------------+---------+------+-----+---------+-------+
| mid            | int(11) | NO   | PRI | NULL    |       |
| quiz_questions | text    | NO   |     | NULL    |       |
+----------------+---------+------+-----+---------+-------+

In the above table, the ids are stored in this pattern     1,5,10,6,7,11,15,29,2   ------------------> Tis are the quiz id.   I'm using this query but to bring the uinque questions but still the same questions are comming..

$q = $this->database()->prepare("SELECT quiz_questions FROM quiz_played WHERE mid = ?");
        $q->bindParam(1, $mid,PDO::PARAM_INT);
        $q->execute();
        $row = $q->fetch(PDO::FETCH_ASSOC);       
        $q->closeCursor();
        $q1 = $this->database()->prepare("SELECT * FROM quiz WHERE qid NOT IN (?) ORDER BY RAND()");
        $q1->bindParam(1, $genre,PDO::PARAM_STR);
        $q1->bindParam(1, $row['quiz_questions'],  PDO::PARAM_STR);
        $q1->execute();
        return  $q1->fetch(PDO::FETCH_ASSOC);

Any help will be really appreciated.
