PHP - Php Error - "uninitialized String Offset: 36"

Hi,

bit stuck on how to find and replace "<" and ">" with "&lt;" and  "&gt;". I basically have a database record that outputs to screen and I need the code in the <code> tags to be rendered to the screen. I therefore need it to go through the whole array variable from the db and change the symbols just inside the code tags. Please be aware that the code tags might happen more than once

here's an example below

Code: [Select]
<p>blah blah blah</p>
<p>blah blah blah</p>
<p>blah blah blah</p>
<code>
<h1>hello</h1>
</code>
<p>blah blah blah</p>
<p>blah blah blah</p>
<p>blah blah blah</p>
<code>
<h1>hello</h1>
</code>

the desired output would be:

<p>blah blah blah</p>
<p>blah blah blah</p>
<p>blah blah blah</p>
<code>
&lt;h1&gt;hello&lt;/h1
</code>
<p>blah blah blah</p>
<p>blah blah blah</p>
<p>blah blah blah</p>
<code>
&lt;h1&gt;hello&lt;/h1
</code>

help on this would be great

Cheers

Rob

Hi guys

I am a newbie with PHP and I have been trying to solve this problem for 3 days..

Ive set up a booking form on my website to be sent directly to my email once the client clicked on the send button..
The problem I am having while checking these pages on wamp is that the booking form is ok but when I click on the send button the following message error appears
"Warning: mail() [function.mail]: Failed to connect to mailserver at "localhost" port 25, verify your "SMTP" and "smtp_port" setting in php.ini or use ini_set() in C:\wamp\www\fluffy_paws\booking_form2.php on line 27"

When I check online I have this message "500 - Internal server error.
There is a problem with the resource you are looking for, and it cannot be displayed."

Are my codes wrong???

My webhosting is Blacknight.com , Im on Windows Vista, my internet is a dongle with O2 ireland

Thanks for your help!

Hi guys

I'm struggling a bit, I need to replace a word that occurs multiple times in text with an array("up","down","forward","backwards") of words.


$find = "left";
$replace = array("up","down","forward","backwards");
$text = "left left left left";

echo str_replace($find,$replace,$text);


The Output is: array array array array

Did try this with a foreach statement as well, but no luck. Is there a better way of doing this? 

Thanks

I've been struggling with being able to send an e-mail via the php mail() function when the body of the e-mail includes a "unique" URL.

The string that will not work is:

"https://p11.secure.hostingprod.com/@www.domain.com/dir/directory/file.ext"


The point within the string that breaks the capability, is the "/" after www.domain.com.  I have tried escaping it like so:

"https://p11.secure.hostingprod.com/@www.domain.com\/dir/directory/file.ext"

This allows the e-mail to successfully send,  however the body of the e-mail contains the backslash as well as the frontslash.

Any ideas?

Hello Everyone,

I am having issues where people are submitting null characters on my website (I.e. %00).  Currently, I check if their is a value by using the empty function, and I also am checking if the value after running the trim command is =="".  How can I check for these special characters to make sure that whatever they are submitting actually contains some sort of legitimate value?

Thanks!

Hi there - can anyone lend me a little advise as to what I'm doing wrong here.

I have this line:
$query=mysql_query("SELECT * FROM gallery a JOIN gallery_image b ON a.id = b.gallery_id where gallery_id=$gallery_id");

I am trying to add an order by statement: order by gallery_image.priority

So I created:
$query=mysql_query("SELECT * FROM gallery a JOIN gallery_image b ON a.id = b.gallery_id where gallery_id=$gallery_id order by gallery_image.priority");

But, I receive the error (even though there is table called "Gallery Image" and a column called "Priority":
Code: [Select]
Warning: mysql_num_rows(): supplied argument is not a valid MySQL result resource in /home/***/public_html/***/gallery.php on line 5
select: Unknown column 'gallery_image.priority' in 'order clause'

Hi, I currently have an if, elseif, else program that starts off with

Code: [Select]
if( $v_name == "" || $v_msg == "" )
echo "something"
how do I turn this into a switch?

but the very next elseif I have

Code: [Select]
elseif( strcspn( $_REQUEST['msg'], '0123456789' ) == strlen( $_REQUEST['msg'] ) )
echo "something"

is it possible to turn this into a switch with 2 different strings like that to evaluate?

Hello all, I'm an amateur at PHP coding, and am currently enrolled in a PHP and MySQL class that uses the PHP Programming with MySQL textbook, by Don Gosselin. I'm trying to get this simple Shopping Cart script to work, because it's the step-by-step example script for Chapter 11, but I keep getting the following errors on ShowCart.php when I try to add an item to the cart. Quote

Warning: mysqli_query() [function.mysqli-query]: Couldn't fetch mysqli in C:\xampplite\htdocs\ShoppingCart.php  on line 78

Warning: mysqli_errno() [function.mysqli-errno]: Couldn't fetch mysqli in C:\xampplite\htdocs\ShoppingCart.php on line 80

I've read "Couldn't fetch mysqli" errors are because the connection was closed prior to those lines, but I don't see any indication of a connection closure. I have no idea what to do, as all the code was given to me in the book, I merely copied it down.

I am getting the error:

Parse error: syntax error, unexpected T_STRING
Which starts on the first line of my requested data ("[request("Id_From")]\n).

Any help on this would be truely appreciated!

Thank you!

So I wanted to create stickers on my forum where people type in say ":Blobby-Tired" and then instead of the comment showing ":Blobby-Tired" it shows an html image tag displaying a picture of Blobby in the comment box

So I created the following page CommentUpload.php

However my sql fails to insert it despite the fact when I "echo $new" it shows the image on the page correctly

And it can't be my sql insert code as if I change $new variable for "$BodyText" int he SQL query it it inserts   ":Blobby-Tired" OK?

 

<?php
include 'dbconnect.php';
session_start();

if(isset($_POST["submit"]) && !empty($_POST["CommentText"])){
$id = intval($_SESSION['id']);
echo  $_SESSION['id'] . '<p> </p>'   ; 
$BodyText = $conn -> real_escape_string($_POST['CommentText']) ; 
$User = $_SESSION['username'];

//Replace flairs with <img> tags 
/*not working currently) */
$new = str_replace(":Blobby-Tired","<img src='flairs/Blobby-Tired.jpg'> </img>","'$BodyText'");
echo "$new";
/************************/ 

	 $sql = "INSERT INTO Posts (User, CommentText, IdOfThread)
     VALUES ('$User','$new','$id')";
     if (mysqli_query($conn, $sql)) {
        echo "New record has been added successfully !";
     } else {
        echo "Error: " . $sql . ":-" . mysqli_error($conn);
     }


     mysqli_close($conn);

}

?>
