Hi All,

Hope you can help, I'm having problems with the strip_tags code, I'm having problems getting it to work with certain tags, the code below shows my issue:


$print_description = <span style="color: #ff99cc; font-size: large">4 x BLUE handmade clay feet</span>

$print_description = strip_tags($print_description); //remove html because of danger of broken tags

I've cut down the code to show the problem. So I want to strip the Span tags; the problem I am having is as soon as you have a style attribute with more than one attribute and you use a ; symbol strip_tag will strip the entire content of the <span>AND ALL THE TEXT IN THE MIDDLE</span>.

I want to just be left with '4 x BLUE handmade clay feet'

If I take the ; out and just have one style it works fine. I am using tiny_MCE so don't have the option not to use what it makes me use.

I've searched the net and have tried a few things to make it work but now I'm at a loss.

Any help would be gratefully received.

In querying my database, I'm Selecting nameFirst and nameLast, and it produces a name like Joe Smith.  I'm trying to match a photo with the name.  Right now I'm uploading photos into a folder naming the file (e.g. SmithJoe.jpg). 

For reasons that involve writers being able to upload and access photos, I'm trying to use an image plugin.  When uploading photos, it strips capital letters, so SmithJoe,jpg goes in as smithjoe.jpg, and it's not matching my database query. 

Here is the code I'm working with that works quite well with this one exception:


$query = 'SELECT * FROM wp_playerRank';
$results = mysql_query($query);
while($line = mysql_fetch_assoc($results)) {

if ($line['wpID'] == $wp_tagID)  {

echo '<div class="player">';


// Here is the code that produces the image.  I need to get rid of capital letters for ease of use

echo '<div><img src="/wp-content/uploads/' . $line['nameLast'] . $line['nameFirst'] . '.jpg"></div>';



echo '<div class="playerData">' . $line['height'] . ' ';
if ($line['position'] == 'PG')  {echo 'Point Guard';}
elseif ($line['position'] == 'SG')  {echo 'Shooting Guard';}
elseif ($line['position'] == 'SF')  {echo 'Small Forward';}
elseif ($line['position'] == 'PF')  {echo 'Power Forward';}
elseif ($line['position'] == 'C')  {echo 'Center';}
echo '</div>';
echo '<div class="playerData">' . $line['hschool'] . '</div>';
echo '<div class="playerData">' . $line['summer'] . '</div>';
echo '<div class="playerData">Class of ' .$line['year'] . '</div>';

if ($line['committed'] == 'y') {
echo '<div>
<br>Committed to <strong>'. $line['college'] . '</strong></div>
';}

}
}

Hey all, i need a function or  a way to replace each letter in a string to a star (*)

Thanks

hello
I want select first 500 char of my text and insert it as intro text and all of them for full.
anyone can help me?

thank you

Hi, I have this very simple code...

<?php
echo "<code>";
$hFile = fopen("myfile.ini","rt");
while(!feof($hFile))
{
$string = trim(fgets($hFile,8));
$c = substr($string,0,1);
if($c!="[" && $c!="\n" && $c!="\r" && $c!="")
{
$i = crc32($string);
echo printf("%8X", $i) ."=". $string ."<br/>";
}
}
fclose($hFile);
echo "</code>";
?>

However, it's returning results like this:
Code: [Select]
4C20553D=4NATION
7BE5EF8C=4RIP
EAAD529E=4SPIDER
4EB7AFA2=4WEED
7367626=4_OR_14
83101629=5CROSS
When I wanted leading 0's, like this:
Code: [Select]
4C20553D=4NATION
7BE5EF8C=4RIP
EAAD529E=4SPIDER
4EB7AFA2=4WEED
07367626=4_OR_14
83101629=5CROSS
I've tried "%.8X", which I figured would work... but it just turned all the hashes to 0.

Also, which other varients of CRC are commonly used? The results I am getting are not what I expected as from another program...

I have the following code:

Code: [Select]
$str = ($stringcontents[$step+38]);
$str1 = ord($str);
$bgcolor = convertchar($str1);
?>
<td bgcolor='<?php echo $bgcolor;?>'>
<span title='<?php echo $fieldname;?>' style='color: <?php echo $fgcolor;?>; font-size: 12pt'><font color="<?php echo $fgcolor;?>"><?php echo $stringcontents[$step];?></font></span>

the convertchar function takes the ord value of the ASCII chr and sets a variable for bgcolor and fgcolor using HTML color codes.  The background sets correctly, but the foreground ASCII chr is always black and does not use the font color code.

What do I need to do to get the ASCII chr to change to a color other than black?


Added:
I am using a default charset:

<META http-equiv="Content-Type" content="text/html; charset=IBM437">

I have a list of pictures and I want to control the order.


Here is the picture format:
$pic = http://www.picture.biz/incoming/w_2GTEK13T961240561_1.jpg
$pic = http://www.picture.biz/incoming/w_2GTEK13T961240561_2.jpg
$pic = http://www.picture.biz/incoming/w_2GTEK13T961240561_3.jpg
$pic = http://www.picture.biz/incoming/w_2GTEK13T961240561_4.jpg
$pic = http://www.picture.biz/incoming/w_2GTEK13T961240561_5.jpg

Notice the order 1.jpg, 2.jpg, etc..

Here is where I'm stuck...

// begin stuck :)
$orderPic = explode("_", $pic);

foreach($orderPic as $rank){
     echo "$rank"; // I need $rank to equal 1 then 2 then 3 ...
}


It would be nice actually if I could start the insert with number 2 because number one is always a screwy picture.

I hope this makes sense /  Thank for the help!

Hi all

I am trying to loop through an array and output as JSON.
What I'm looking to do is create something like:

Code: [Select]
  "something": [
{"title":"Test 1"},
{"title":"Test 2"}
],

Notice that the final row has no comma.

My code is as follows:


<?php foreach($something as $thing): ?>
<?php $something_array = array('title'=>$thingt->getId()); ?>
<?php echo json_encode($something_array).','."\n"; ?>
<?php endforeach; ?>


I had to add a comma to the end of the array, or the JSON rows would not be ended with one.

How can I get it so that, no matter how many items are in the array, the last row, wil not have the comma at the end?

With the comma at the end, my JSON doesn't validate

Thanks


[/code]

Code:

Code: [Select]
PostInfo,color-main,Newman,not-collapsed;Friends,color-main2,Top Friends,not-collapsed||Twitter,color-main2,Twitter,not-collapsed;Signature,color-main2,Signature,not-collapsed;AboutMe,color-transparent,About Me,not-collapsed

Now I want make a function like

if PostInfo = "not-collapsed" = do this/etc,


So simply, how do I extract some content out of this and then use each thing to equal to if it's 'not-collapsed' or 'collapsed' ?

Very hard but i think possible? ty

Hi guys, I am writing a "login" script  that will be on my main page(I have it inside of <head></head> tags). I want it to take a user name and password, store it in a variable that is persistant with all pages on my website. Is that possible? How can I make a variable that will carry over to a page that doesn't have the original code? E,g, $Login = "alogin"; then when my client goes to a different page $Login still == "alogin"?
I hope this is understandable.
I am not writing a very advanced script, I just want the input form to store the users login name/password so he or she may access a section of the site that has more options available if they're logged in.
