PHP - Hiding Text On A Page

I'm normally fairly proficient with PHP, but I haven't done any coding in quite a while, so I'm a little rusty.

I have an entire page of text from which I need to extract a single value. Here is a small portion of the page in question:

Code: [Select]
Total Rank: 128
Total Points: 4,978
Next Rank: 20

For instance, I need to extract the values "128" "4978" and "20" and store them in variables. These values change all the time, so I'm not sure what the best way to go about this is... maybe a regular expression  ? If that's the case, I've never been too good with them, so any help would be appreciated.

I currently have a mailing list that my boss uses, when he adds an email there is no 'sucess message' to let him know it has worked.   The mailing list just redirects back to the add subscribers page. I wondered if its possible to add a request so when he adds an email I can redirect the url to this:   ?page=addemail&message=your email was added   and then echo $message where I want it to appear.   I have added $message = $_REQUEST['message']; to my page but nothing is happening. Can I not use request like this?

Hello,
What if I wanted to publish a php program but want to hide the code so that even buyers would not get a look at it despite having the program fully functioning on their servers, is there a means through which I can hide the code so that it won't be shown even when the .php files are opened in a text editor?

Hi!

I have got an array which contains messages for different types of errors on my website (for login errors and such). My problem is however, that when the array is empty it still shows the message box (the CSS).

here is the code I am using:

Code: [Select]
    public function showMessages() {
        if (count($this->_messages > 0)) {
            echo '<div id="messages">';
            foreach ($this->_messages as $msg) {
                echo $msg . '<br />';
            }
            echo '</div>';
        }
    }

I am starting to think that I need to be doing this in JavaScript. I would prefer to do it using PHP only, if it is possible though.

Thanks for the help!

Hi all

I have a website which has a payment system on it, I use sagepay, paypal and a few others.

They all have relatively similar forms, in which the total amount to be paid is passed in a hidden form field, such as

<input type="hidden" name="amount" value="25">

all the payment gateways I use have the same or similar method to send the total amount (ie: 25)

for example, my paypal form is like

<form action="https://www.paypal.com/cgi-bin/webscr" name="paypal_form" method="post">">
    <input type="hidden" name="cmd" value="_xclick">
    <input type="hidden" name="item_name" value="items">
    <input type="hidden" name="currency_code" value="GBP">
<input type="hidden" name="notify_url" value="complete.php">
<input type="hidden" name="return" value="complete.php">
<input type="hidden" name="cancel_return" value="complete.php">
    <input type="submit" name="submit" value="PayPal" />
</form>

this is all fine, apart from the user can use things like "firebug" to alter the total to be paid, so they can change $25 to $4 for example.

So my question is, is there anyway with PHP to send over these form values are hidden variables.

My idea was to post my form fields apart from the "cost" to a PHP script, then get PHP to grab the total from the database and dump the value in cost field and send it along with the other posted values.

So really, is there anyway to get PHP to process a form data in a hidden enviroment, so my payment form URL is something like

process.php

and then process.php on my server deals with the sending of the paypal form data, but in a way that the user cannot see this data, so they basically never get to see the paypal form and any of its contents.

Hopefully that kind of makes sense

I have tried so many ideas, but cannot seem to find a solution, although when I do, hopefully the same method can be used on all my payment forms.

Thanks tons in advance

When I display my database entries, I want to hide some of the data.

As you can see in this example:
http://www.beat-the-spread.net/week1.php

What I'd like to do is leave all the cells blank where the spread is zero.

Here's the code I'm using:
Code: [Select]
while($row = mysql_fetch_array( $result ))
{
$i=1;
if ($row['game_id']='$i')
{
echo "<tr><td>"; echo $row['date'];
echo "</td><td>"; echo $row['team_name'];
echo "</td><td>"; echo $row['owner'];
echo "</td><td>"; echo $row['pt_spread'];
echo "</td><td>"; echo $row['team_pts'];
echo "</td><td>"; echo $row['team_bet'];
echo "</td><td>"; echo $row['team_cover'];
echo "</td><td>"; echo $row['owner_pts'];
echo "</td></tr>";

if ($table_row_count % 2 && $table_row_count != 0)
{
echo ' <tr style="height: 8px"></tr> ';
}
$table_row_count++;
}
$i++;
}
echo "</table>";

I've been fooling with this for a couple hours and can't seem to find a decent way to do this.
Can anybody help with this? Thanks.

Hi,

Wonder if someone could help with the problem below. Got a main page that includes a header, footer and a link to a database. I can get the two Includes to work but can't seem to display the database fields in the body of the page. What has me baffled is that it appears to be connecting to the database, (Opening the connection to the database server The connection worked. The link is: Resource id #3) but no text (see below for database text) is appearing on the screen. Yet I'm not getting a "page_not_found" message. I can go to the database in MYSQL console and query it successfully. Read and (hopefully) applied the section Debugging: A Beginner's Guide, but still can't see the problem. Any help greatly appreciated.

I have a dynamic menu (jglidemenu) installed on my site.  It works fine on my HTML pages but on my PHP pages the font formatting from the menu's style sheet isn't working and I haven't been able to figure out why.

Here's a page where the menu is working correctly:

http://www.greenbayeasthighschool.com

and here's a page where the formatting fails:

http://www.greenbayeasthighschool.com/staff_by_lastname.php

This is my first attempt at creating a page with PHP.  Is it not possible to use CSS formatting on a page that includes PHP content?

Thanks in advance for any help.

First and foremost, I am a PHP novice so, if there's better or more efficient way of doing what I'm trying to do, please feel free to point it out

I came across an old PHP script that was used to crawl a site and check the response code on the pages found. I have modified it to do a duplicate content check. It's using the similar_text function to compare 1 page's content (specified by the user) against the content of each page it finds.

It's a little slow but, its working. The only problem that I'm having is that it stops after about the first 10 links and I can't figure out why.

Any help is greatly appreciated.

Hi,

I want to show part of the text from a page containing my article on my main page. The article resides in a database in mysql. How do I limit the amount of text that is shown without setting up a separate excerpt box for the article. I want to then provide a link so the user can go to another page that displays the entire article. Thanks for any suggestions.

I am trying to hide the image filepath and found this tutorial http://www.bounmis.com/en/PHP/How_To_Hide_Image_Source.html which I am currently using. It works but I need an additional security here so this script parses images only if the user is logged in to wordpress

here's what i have so far:

if ( is_user_logged_in() ) {
   $file=$image_path.'authorized.jpg';
} else {
  $file=$image_path.'notauthorized.jpg'; 
};

    if (file_exists($file)){

        $img=@imagecreatefrompng($file);
    }
    ImageJpeg($img);
    imagedestroy($img);
}
?>

the script doesnt work. I think it's because i set headers Header('Content-type: image/jpeg'); What can I do to make it work?
Please help

thanks
