PHP - Problem Escaping A Percent Sign

Im getting a syntax error caused by the first line. How do I properly escape the code? echo "<tr class="'.$colors[$i++ % 2].'">
<td align=center  nowrap>($phone1) XXX-$phone2</td>
<td align=center  nowrap>$overall</td>
<td align=center  nowrap>$hygiene</td>
<td align=center  nowrap>$attitude</td>
<td align=center  nowrap>$ethnicity</td>
<td align=center  nowrap>$body</td>
<td align=center  nowrap>$city</td>
<td align=center  nowrap>$user</td>
<td align=center  nowrap>$date</td>
<td align=center  nowrap>$comment</td>
</tr>";

Hi,

I have set up a simple function so that when a user enters a title in a php form, php gives the first letter of each word a capital letter. As follows:

function caps($text){
$search_text=$text;
$search_text=ucwords(strtolower($search_text));
$look_for = "(a";
$change_to = "(A";
$changed_text = str_replace($look_for, $change_to, $search_text);
$search_text=$changed_text;
$look_for = "(b";
$change_to = "(B";
$changed_text = str_replace($look_for, $change_to, $search_text);
$search_text=$changed_text;
$look_for = "(c";
$change_to = "(C";

//...etc...etc.. up to

$look_for = "(z";
$change_to = "(Z";
$changed_text = str_replace($look_for, $change_to, $search_text);
$search_text=$changed_text;
return $search_text;

}

The trouble is, if I were to enter the following "The secret of DNA", my function would return "The Secret Of Dna" (removes the caps). Any ideas how to get around this would be most useful. Thanks in advance.

echo "<td style="background-color:#fff"
 onMouseover="this.style.backgroundColor='#ff9900';"

Hi Php Freaks

Hello!

I'm very new to PHP, and I'm sure this is a noob question - still, its got me stuck!

How would I best escape this properly?

$resizeObj = new resize('C:\xampp\htdocs\images_test\$file');

so that $file is parsed?

the whole script is as follows:

Code: [Select]
<?php
// *** Include Nathan's class
include("resize-class.php");

// Define the full path to your folder from root 
$path = 'C:\xampp\htdocs\images_test'; 

// Open the folder 
$dir_handle = @opendir($path) or die("Unable to open $path"); 

    // Loop through the files 
    while ($file = readdir($dir_handle)) { 

    if($file == "." || $file == ".." || $file == "index.php" ) 

        continue; 

// *** 1) Initialise / load image
$resizeObj = new resize('C:\xampp\htdocs\images_test\$file');
// *** 2) Resize image 
$resizeObj -> resizeImage(100, 100, 'auto');
// *** 3) Save image
$resizeObj -> saveImage('C:\xampp\htdocs\images_test\$file', 90);

        echo "<a href=\"$file\">$file</a><br />"; 
echo $path;

    } 
    // Close 
    closedir($dir_handle); 



?>

I have a table with two columns A and B.  I'm submitting a form where the user selects different checkboxes.   Column A contains the values of all the checkboxes.  I want to, after the form is submitted, using the array of values of randomly checked checkboxes, search the table for the corresponding values in column B.  Then display the values of selected checkboxes and their cosesponding values from column B. 
First I did an implode() on the array of submitted checkbox values,
Code: [Select]
$list = "'".implode("','", $_POST['Ref'])."'"; then did a mysql_real_escape_string on that.
Code: [Select]
for($i=0;$i<$count;$i++)
     {
$list = mysql_real_escape_string($list[$i]);
} I got a
Warning: mysql_real_escape_string() [function.mysql-real-escape-string]: Access denied for user 'SYSTEM'@'localhost' (using password: NO)
Warning: mysql_real_escape_string() [function.mysql-real-escape-string]: A link to the server could not be established
for each row of $list.
What am I doing wrong? 

Do I need to escape variables passed via link? Is it possible that someone does an SQL Injection via unescaped $_GET variable? (Yes I am using it in an SQL query, not inserting it into a DB tho)

I've got this code and it works fine.  All I want to do is, when people click on the x to delete something they submitted erroneously, I want a confirmation...really want to delete this?  (sometimes that x is too tempting you know)

But I *think* I'm having trouble escaping the line (near bottom):  onsubmit='".return confirm('Really Delete');."'

I'm not sure if it will work anyhow...but right now it doesn't.

Thanks for any suggestions.

I am passing this value:

Quote

\\"''"""\""\\\\""""''''\"""\\\""''""""'/'/'/\"'\'\\'\\''\\'''''


the the following code is not handling it correctly:


$data = mysql_real_escape_string(strip_tags(htmlspecialchars($data)));


here is what it looks like when the server gets it:

Quote

\\"''"""\""\\\\""""''''\"""\\\""''""""'/'/'/\"'\'\\'\\''\\'''''



and here is after the code executes:

Quote

\\\\&quot;\'\'&quot;&quot;&quot;\\&quot;&quot;\\\\\\\\&quot;&quot;&quot;&quot;\'\'\'\'\\&quot;&quot;&quot;\\\\\\&quot;&quot;\'\'&quot;&quot;&quot;&quot;\'/\'/\'/\\&quot;\'\\\'\\\\\'\\\\\'\'\\\\\'\'\'\'\


Notice if I have

Quote

\'


it bugs out.

I have a html form with a wusiwug editor when i selete an image it generates the code for that img like

<img src="http://www.abc4blinds.co.uk/editor/elfinder/files/icons%20social.png" width="33" height="35"> 

but when i submint it

it gives me <img src="%5C" http:="" www.abc4blinds.co.uk="" editor="" elfinder="" files="" icons%20social.png\="" 33\="" 35\="" width="\" height="\"> 

why i am not running any vailidation all i am doing is accessing it in $_POST['article']

<td><textarea name="article" cols="85" rows="5" id="article"><?php echo $_POST['article']; ?></textarea></td>

I've got a file with some strings that have both types of quotes in them.  And I seem to have managed to get the data, display it in my html, store it in a js array (using a json_encode in php and then simply inserting it into my js) but I cannot seem to pass the string as a parameter form an onclick function call to js.    For most strings the addslashes makes it work in the function call.  But for those with both sets of quotes it won't work.  My console tells me there are "unterminated string constants..".  I've experimented with many silly changes but none make it work.   Ex. of the strings:   What do you mean "It's crooked"?   Of course I could remove the contraction and that would probably work, but that would be a hack, would not it?

This should be really simple but I can't get my head round it.

Please see the PHP/HTML below.


<?php
$a = array(

'test' =>

"'data'"
);
$json = json_encode($a);
?>

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>Unknown Page</title>
<script type="text/javascript" src="http://ajax.microsoft.com/ajax/jquery/jquery-1.5.min.js"></script>
<script type="text/javascript">
var j = jQuery.parseJSON('<?php echo $json; ?>');
</script>
</head>
<body>
</body>
</html>


You will notice that data is stored by " then '
I have tried how it is and also with add slashes


$a = array(

'test' =>

addslashes("'data'")
);

It either outputs without slashes (which is clearly wrong)
Code: [Select]
var j = jQuery.parseJSON('{"test":"'data'"}');Or which I cant work out why dosent work
Code: [Select]
var j = jQuery.parseJSON('{"test":"\\'data\\'"}');
Now firebog throws the following error
Code: [Select]
missing ) after argument list
How should I be escaping this variable?

What is the correct way to echo this line???
Quote

<php?
echo "proceed to <a href= <?php echo urldecode($_GET['url']); ?>> <?php echo urldecode($_GET['title']); ?>   </a>";
?>


My Parse error says:
