Looking For A String Within Some Text And Wrapping It With A Link

Similar Tutorials

View Content

I am trying to wrap a string with an anchor tag if it finds a match with a block of text. Here is an example text block:

CONOCO 1'10x8 VC DF TP SGN||PRINCIPAL ILLUMINATION||ENG: CO3028TP_0VPR||DWG: CO200428||TO BE: DYED DIESEL (SPEC)||

The string I would want to wrap with a link would be "CO200428".

The next problem is the drawings (what I'm searching the text for) has over 115,000 possibilities. The text blocks to search are over 1300.

I have the drawing names stored in a simple mysql table...but doing a foreach takes forever...I imagine it will take even longer when looking in the text blocks...

Is there a way to easily to do the anchor wrap? I don't know regex very well...

Hi,

I have a small code to display some data from mysql db as .png image, however the image loads but it doesn't show any data on it.

php:


<?

    $username="";

    $player_name=$_GET['player_name'];



    mysql_connect($host,$username,$password);

Imagettftext() Failure

I'm writing a Dynamic image, that display's a user's Name, but for some reason, the kills stat won't print. I made a .php file using the same parsing method, but using echo, and it worked fine. I also know it's not an issue with X,Y, Size, float, anything like that because I tried replacing "$kill" with "Test," and it printed fine.
Here is the actual image:

And here is the code for it:
<?php

Imagettftext() - Just can't get it to work

Hi ALL

I'm trying to create a simple font tester. Imagettftext() looks perfect but I can't get it to work. I'm using this piece of code from php.net.

Hello i have some code which is suppose to create a simple captcha image...the code was working fine until it was moved from one location to another...now what it does is the image is created...but for some reason, it's not displaying the text.
Here is my code :
Code: [Select]
<?php
session_start();

$image = imagecreate(100, 50);

$background = imagecolorallocatealpha($image, 204, 204, 204, 127);

$text = imagecolorallocate($image, 0, 0, 0);

imagettftext($image, 20, 0, 30, 30, $text, 'Gabriola.ttf', $_SESSION['captcha']);

$lines = 20;

for($i = 0; $i <= $lines; $i++){
    $x1 = rand(1, 100);
    $y1 = rand(1, 100);
    $x2 = rand(1, 100);
    $y2 = rand(1, 100);

    imageline($image, $x1, $y1, $x2, $y2, $text);
}

header('content-type: image/jpeg');
imagejpeg($image);

?>
this code does create the gray box and displays the 20 lines but no text. when i echo out the $_SESSION['captcha'] on the page it displays the number generated (generated in another file)....i've even replaced that with a string and it doesn't work...the interesting thing about it is that it works on local machine but not on a hosted page...what could possibly cause this?...all the files were changed so the .ttf file is also within the same file as this page

Hi All,
I am getting this problem for one of my site that i am developing .
When I insert special characters string like thi's ~!@#$%^&*()_+| the code is unable to convert it into right image with all text on it when the chosen font in trajanpro.ttf, but when I change the font with Ariel it work's fine.
If anyone want to check this problem then you can check at this link

http://www.centralstationery.com/produc ... ate_id=231

Click the text on card and a pop up will open and then change the font to Ariel then the image on card will be converted into right text.

The code is

imageSaveAlpha($image, true);
ImageAlphaBlending($image, false);
$bgcolor = imagecolorallocate($image, 200, 200, 200);
$transparentColor = imagecolorallocatealpha($image, 200, 200, 200, 127);
imagefill($image, 0, 0, $transparentColor);
// pick color for the text
$fontcolor = imagecolorallocate($image, $red, $grn, $blu);

// fill in the background with the background color
imagefilledrectangle($image, 0, 0, $width, $height, $transparentColor);
$x = 0;
$y = $fontsize;
imagettftext($image, $fontsize, 0, $bx, $by, $fontcolor, $font, $quote);

$final_image=DIR_USER_EDITOR.$new_image;

// output image to the browser
imagepng($image, $final_image);

// delete the image resource
imagedestroy($image);

Having Font Size Troubles With Imagettftext

Similar Tutorials

View Content

I need to draw various font sizes onto a canvas to create a web service. Wanting to protect my HD assets, the intent is to use PHP to populate the image with the necessary text, and then scale down the image before presenting it to the user.

A similar service already exists, a tool to allow the public to make user generated content for a card game.

The problem ever, is that PHP does not seem to handle font sizes very well. I created this sample code to demonstrate my issue.
Here is a sample output from the code below

<?php
    $img = imagecreatetruecolor(750, 530);
    
    $black = imagecolorallocate($img, 0, 0, 0);
    $gray = imagecolorallocate($img, 125, 125, 125);
    $white = imagecolorallocate($img, 255, 255, 255);
    
    $font = realpath('../fonts/micross.ttf');
    
    $size = 12;
    $spacing = 20;
    
    for ($x = 0; $x <= 25; $x++) {
        $box = imageftbbox($size + $x/10, 0, $font, "The longer the phase the more apparent the size difference should be");
        $boxWidth = $box[2] - $box[0];
        
        imagefilledrectangle($img, 5, $x*$spacing+5, $boxWidth+5, ($x+1)*$spacing+5, $gray);
        
        imagefttext($img, $size + $x/10, 0, 5, $spacing*($x+1), $white, $font, "The longer the phase the more apparent the size difference should be Font Size ".($size+($x/10)));
    }
    
    imagejpeg($img);
    imagedestroy($img);
?>

You can see how despite the font size steadily increasing by 0.1, it sporadically jumps at what seem at first like random intervals, however if you increase the number of loops and log the data, you can see that it alternates between increasing every 0.7, and 0.8. Unfortunately that doesn't help me any, just some insight.

if($last != $boxWidth)
{
    $last = $boxWidth;
    echo $boxWidth." ".($size+($x/10))."<br>";
}

This outputs the current width and font size each time the text width changes.
I've compiled a sample output for you guys to look at here

Hopefully I've provided enough information to get some help, this has been very frustrating.

Imagecreate, Imagettftext And Font Path Error

Similar Tutorials

View Content

Hi,

I am creating an image with a random number to use as a capcha. I've done the image creation before and had it working but now I have a font path error.

However......I know my font path is the same...I didn't change it and it was working perfectly. What I changed was I made the image creation piece of code into a function...so I could return a value and use the function as a capcha....can you not use this image creation stuff in a function?

The difficulty is getting hold of the random number to verify someone typed it correctly. If you have any ideas I'm open to other methods.

My code is:
function capcha(){
   $capchatxt = rand(10000,99999);

   $font = '/includes/balloon.ttf';
   $textarray = imagettfbbox(30, 0, $font, $capchatxt);
   $width = $textarray[2]-$textarray[0];
   $height = $textarray[3]-$textarray[7];


      $image          = imagecreate($width+10,$height+10);
      $background = imagecolorallocate ($image, 255,227,232);
      $colour       = imagecolorallocate($image, 0, 154, 239); // blue;
      $pink          = imagecolorallocate($image, 239, 0, 144); // crimson pink;
      $peach          = imagecolorallocate($image, 255, 227, 232); // pale pink;

   // Add the text
   imagettftext($image, 30, 0, 5, $height+5, $pink, $font, $capchatxt);

   header('Content-type: image/png');
   imagepng($image);
   imagedestroy($image);
   return $capchatxt;
}

At the moment: The function and the font file are in the same folder. The file which is calling the function is in a different folder.

BTW - Forgot to mention that right now I'm using localhost (xampp)...not a real server.

Thanks for the help.

Wrapping While Loops In Divs

Hello guys! I'm currently writing a bit of an image gallery code which is working pretty well however there seems to be a few issues with the sytling and layout of the gallery. (It's nothing flash just displays the images and caption in category order) Now I am not sure how to go about doing this but is there any way to wrap each category in a div? I have the whole while loop wrapped in a div at present but I would like each category wrapped so I can style it a bit easier. Can someone please point me in the right direction. Currently my code looks like this:

function Gallery(){

    ini_set('display_errors',1);
    error_reporting(E_ALL);

    $conn = mysqli_connect("Why","Hello","There","Friends")
        or die('Cannot Connect to the database');

    $q ="SELECT * FROM gallery_category AS c JOIN gallery_photos AS p ON p.categoryname = c.categoryname ORDER BY c.categoryid";
    $result = mysqli_query($conn, $q)
        or trigger_error("Query Failed! SQL: $conn - Error: ".mysqli_error(), E_USER_ERROR);


    echo"<div class='gallery'>";
    $categoryname='';
    while($rows = mysqli_fetch_assoc($result)){

            if ($categoryname != $rows['categoryname']) {
                    $categoryname = $rows['categoryname'];

                    echo"<div class='h'><h2>".$rows['categoryname']."</h2></div>";

                }

                echo"
                    <div class='gall'>
                        <div class='gl-img'><img src='pathway/to/gallery/".$rows['photoname']."' alt='".$rows['categoryname']."'/></div>
                        <div class='gl-cap'>".$rows['photocaption']."</div>
                    </div>";
        
            }


    echo"</div>";

    $conn-> close();
}

I don't know how to go about updating it so that it is this section that is wrapped whilst the "gall" class repeats (if that makes sense)

echo"<div class='h'><h2>".$rows['categoryname']."</h2></div>";
                }
                echo"
                    <div class='gall'>
                        <div class='gl-img'><img src='pathway/to/gallery/".$rows['photoname']."' alt='".$rows['categoryname']."'/></div>
                        <div class='gl-cap'>".$rows['photocaption']."</div>
                    </div>";

So that it looks like this:

<div class="category">
			<div class="h"><h2>Category Title</h2></div>
			<div class="gall">
				<div class="gl-img"><img src="pathway/to/gallery/polarbear2.jpg"></div>
				<div class="gl-cap">Polar Bear</div>
			</div>
			<div class="gall">
				<div class="gl-img"><img src="pathway/to/gallery/polarbear2.jpg"></div>
				<div class="gl-cap">Polar Bear</div>
			</div>
			<div class="gall">
				<div class="gl-img"><img src="pathway/to/polarbear2.jpg"></div>
				<div class="gl-cap">Polar Bear</div>
			</div>
			<div class="gall">
				<div class="gl-img"><img src="pathway/to/gallery/polarbear2.jpg"></div>
				<div class="gl-cap">Polar Bear</div>
			</div>
		</div>

Any and all help on how to achieve this would be appreciated!! thank you

Wrapping External Class

Hi guys! I have a specific requirement and need some help

Say i have an external api library with Client class looking like this:

class Client 
{ 

  some constants.. 
  private props.., 

  __construct() 

  public static function create($url) 
  { 
      some code 
  } 

  public static function authenticate($token) 
  { 
      some code 
  } 

  ...dozen other methods 
}

Current way of instantiating in every single other class where i need the client:

use Client; 

MyFetchController 
{ 
	private $client; 
	
	public function __construct() 
	{ 
		$this->client = Client::create(getenv('URL'))->authenticate(getenv('TOKEN')) 
	} 

	$this->client->use other methods in Client class 
}

Is there a way to wrap that class so i have external parameters loaded through .env file automaticaly available on new wrapper class intialization with something like this:

MyFetchController 
{ 
	private $client; 

	public function __construct(WrappedClient $client) 
	{ 
		$this->client = $client 
	} 

	public function getData() 
	{ 
		$data = $this->client->parse(...) 
	} 
}

Basically what i need is a class ready for DI in all other classes without inserting required auth and other parameters in constructor every single time

Test Line Length For Wrapping

How can I test if a chunk exceeds the image size and wrap that text to the next line. Not sure if I am even doing this correctly with my if statement.

    $text="Lorem Ipsum Lorem Ipsum Lorem Ipsum Lorem http://somelongurl.com/then-we-make-it-super-long-with-some-more/ Lorem Ipsum Lorem Ipsum Lorem Ipsum http://www.anotherlinks.com/";

    $string_chunks = explode(' ', $text);

    foreach ($string_chunks as $chunk) {

        if($end_x + $chunk > $image_width){
            $start_x = 5;
            $start_y += 20;
        }

       $coords = imagettfbbox($fontsize, $angle, $font, $chunk);

       $end_x = $coords[0] + $coords[4] + 10;

       $color_to_draw = is_a_url($chunk) ? $linkcolor : $black;

       imagettftext($im, $fontsize, $angle, $start_x, $start_y, $color_to_draw, $font, $chunk);

       $start_x += $end_x;
    }
With this code I get:

Lorem Ipsum Lorem Ipsum Lorem Ipsum Lorem
http://somelongurl.com/then-we-make-it-super-long-with-some-more/
Lorem Ipsum Lorem Ipsum Lorem Ipsum http://www.anotherlinks.com/

What I would like to happen is something like:

Lorem Ipsum Lorem Ipsum Lorem Ipsum
Lorem http://somelongurl.com/then-we
-make-it-super-long-with-some-more/
Lorem Ipsum Lorem Ipsum Lorem Ipsum

Javascript Onmouseover Wrapping Php Dynamic Content

Similar Tutorials

Hi there,
I know that php does not recognize onMouseOver events. however, Im wondering if their is a tricky way to get a javascript response from dynamic text. I am working on a nav menu in a wordpress site. wordpress has a function that displays a list of pages created in the admin. I want to be able to display a secondary list of pages when a top-level nav item is moused over. heres the code:
<div id="top">
<script type="text/javascript">
function Show(who) {
Clear();
divel=document.getElementById("drop"+who);
divel.style.display="inline";
divel=document.getElementById("hn"+who);
divel.className="selected";
}

function Hide(who) {
divel=document.getElementById("drop"+who);
divel.style.display="none";
divel=document.getElementById("hn"+who);
divel.className="";
}

function Clear() {
for (i=1;i<=3;i++) {
divel=document.getElementById("drop"+i);
divel.style.display="none";
divel=document.getElementById("hn"+i);
divel.className="";
}
}
</script>

<div id="home-nav" onMouseOut="Clear();">
<ul>
<li id="hn1"><a href="wp_demo/profile" onMouseOver="Show('1')"><?php wp_list_pages(include=4&title_li=' ); ?></a></li>
<li id="hn2"><a href="wp_demo/services" onMouseOver="Show('2')"><?php wp_list_pages( 'include=6&title_li=' ); ?></a></li>
<li id="hn3"><a href="wp_demo/portfolio" onMouseOver="Show('3')"><?php wp_list_pages( 'include=8&title_li=' ); ?></a></li>
<li id="hn4"><a href="wp_demo/contact" onMouseOver="Clear();"><?php wp_list_pages( 'include=12&title_li=' ); ?></a></li>
<li id="hn5"><a href="wp_demo/hospitality" onMouseOver="Clear();"><?php wp_list_pages( 'include=10&title_li=' ); ?></a></li>
</ul>
</div> 

<div id="wrapper">

<div id="drop1" onMouseOver="Show('1')" onMouseOut="Hide('1')">
<img src="<?php bloginfo('stylesheet_directory'); ?>/images/blank.gif" alt="" width="960" height="8" border="0" /><br />
<div id="menu1"><ul>
<?php wp_list_pages( 'child_of=4&sort_column=menu_order&title_li=' ); ?>
</ul></div></div>

<div id="drop2" onMouseOver="Show('2')" onMouseOut="Hide('2')">
<img src="<?php bloginfo('stylesheet_directory'); ?>/images/blank.gif" alt="" width="960" height="8" border="0" /><br />
<div id="menu2"><ul>
<?php wp_list_pages( 'child_of=6&sort_column=menu_order&title_li=' ); ?>
</ul></div></div>

<div id="drop3" onMouseOver="Show('3')" onMouseOut="Hide('3')">
<img src="<?php bloginfo('stylesheet_directory'); ?>/images/blank.gif" alt="" width="960" height="8" border="0" /><br />
<div id="menu3"><ul>
<?php wp_list_pages( 'child_of=8&sort_column=menu_order&title_li=' ); ?>

</ul></div></div>

Does anybody know a trick to get the dynamic text to be seen by the javascript? for example, if i put a   inside the anchor tags before the php script starts, the onmouseover will register it, and display the secondary nav. I would place invisible divs with links on top of the dynamic text with z-index, but I want the text to be completely dynamic and the client to be able to add as many links as he/she wants.

thanks!

String Returned By Variable Not Working Like The Same String Entered Manually

Similar Tutorials

Hi,

I am trying to make some adjustments to uploadify.php which comes with the latest version of uploadify (3.0 beta), so that it works with a session variable that stores the login username and adds it to the path for uploads. Here is uploadify.php as it currently looks:

Code: [Select]
<?php
session_name("MyLogin");
session_start();

$targetFolder = '/songs/' . $_SESSION['name']; // Relative to the root

if (!empty($_FILES)) {
$tempFile = $_FILES['Filedata']['tmp_name'];
$targetPath = $_SERVER['DOCUMENT_ROOT'] . $targetFolder;
$targetFile = rtrim($targetPath,'/') .'/'. $_FILES['Filedata']['name'];

// Validate the file type
$fileTypes = array('m4a','mp3','flac','ogg'); // File extensions
$fileParts = pathinfo($_FILES['Filedata']['name']);

if (in_array($fileParts['extension'],$fileTypes)) {
move_uploaded_file($tempFile,$targetFile);
echo '1';
} else {
echo 'Invalid file type.';
}
}

echo $targetFolder;

?>
I added Code: [Select]
echo $targetFolder; at the bottom so that I could make sure that the string returned was correct, and it is, i.e. '/songs/nick'. For some reason though, uploads are not going to the correct folder, i.e. the username folder, but instead are going to the parent folder 'songs'. The folder for username exists, with correct permissions, and when I manually enter Code: [Select]
$targetFolder = '/songs/nick';all works fine. Which strikes me as rather strange. I have limited experience of using php, but wonder how if the correct string is returned by the session variable, the upload works differently than with the manually entered string.

Any help would be much appreciated. It's the last issue with a website that was due to go live 2 days ago!

Thanks,

Nick

Dynamic Image Script That Handles Text Wrapping?

Similar Tutorials

View Content

I am looking for a dynamic image script that handles word wrapping and possible font resizing.

Basically, I have a dimensions, a font and a company name. So, lets say I am trying to make a 300x300 image for Bob's Boats in verdana. I want a script that not only creates the image, but tries to use up the available space (putting each word on a line, using a large font, horizontally and vertically aligning everything)

Worst case I'll write my own, but the algorithm seems pretty complex. For example, lets say the companies name was: Chocolates in a Basket, it could be:

Chocolates
in a Basket

Or:

Chocolates
in a
Basket

But never:

Chocolates
in
a
Basket

Worst case, I might make it so that it supports 3 lines, but only ever puts the company name on 2 by default, and if the user wants to manually change it, they can. Even that isn't perfect though, because if the dimensions are something like 300x35, you wouldn't want a second line, let alone a 3rd.
