PHP - Replace Text With Case Sensitive Input

Short question: How can I get a string of HTML code and replace all the <input> tags with their values?

Long question: I have a web page with a purchase order on it in HTML format and one or more of the columns is editable via input boxes. So the user can change the quantity/length of the material before submitting it. Once they choose to save it, it sends the string of HTML to a PDF generator (DOMPDF) which converts the HTML to a PDF file and saves it to the server. The user then has a hard copy of the purchase order PDF saved for each job. The problem is DOMPDF doesn't do well with <input> tags, it just leaves them as a blank space. So I want to take that string of HTML and replace all input boxes with their values before sending it to DOMPDF.

Currently I'm using Javascript to do just that when the user clicks to save the modified purchase order. The problem with this is it only works for when the user modifies the purchase order and saves a new modified copy. I need to save a base unmodified copy of it when the page loads so this would strip all the input boxes from the page as soon as it loads and the user would no longer be able to edit anything. So I need something to send the string to DOMPDF when the page loads but not modify what's on the page. Any ideas? Thanks.

I'm testing out small bits of code for myself, and I'm trying to understand why this isn't coming out how I would imagine it to...

I have my function which stores colors in an array from a text file, then I return back a random color from my array like so...

function getColor() {
$ball_color = explode("\n", file_get_contents('colors.txt')); // Takes file contents and stores them into an array.
return $ball_color[array_rand($ball_color)];
}

And now in the main program, I simply have this:

$color = getColor();
switch($color) {
Case "blue":
     // echo stuff
        break;
    Case "red":
     // echo stuff
        break;
    etc... 
}



For some reason though, my switch statement always reads the default case, making me assume that the words "blue" "red" "green" etc... aren't matching up to what I have set the cases at. When I output what color is actually being read, it displays exactly as it should, so I don't understand why the case "red" isn't opening up when that color is chosen, or same with any of the other colors.

Is there some small conflict I'm unaware of in this tiny practice code? Any help is appreciated, thanks.

Hi people, I really hope you guys can help me out today. I'm just a newbe at php and i'm having real trouble.

Bassically all I want to do is have a user type in a company name in a html form.

If what the user types in the form matches the company name in my php script i want the user to be sent to another page on my site.

If what the user types in the form doesnt match the company name in my php script i want the user to be sent to a differnt page like an error page for example.

this is my html form:

Code: [Select]
<form id="form1" name="form1" method="post" action="form_test.php">
  <p>company name:
    <input type="text" name="company_name" id="company_name" />
  </p>
  <p>
    <input type="submit" name="button" id="button" value="Submit" />
  </p>
</form>
And this is the php code I'm trying to process the information on:

Code: [Select]
<?php

$comp_name = abc;

if(isset ($_POST["company_name"])){
 if($_POST["company_name"] == $comp_name){

     header("Location: http://www.hotmail.com");
exit();
 }

else{
   header("Location: http://www.yahoo.com");
exit();   
 }
}
?>
The thing is i'm getting this error when i test it:
Warning: Cannot modify header information - headers already sent by (output started at D:\Sites\killerphp.com\form_test.php:10) in D:\Sites\killerphp.com\form_test.php on line 17

Please can some one help me out, i'm sure this is just basic stuff but i just cant get it to work 

Cheers.

Hi! Basically, I'm making a PHP file that lists things from a file, so if the file contained; '@-Line 1-@@-Line 2-@' it would produce <li><a href="#">Line 1</a></li><li><a href="#">Line 2</a></li>, but I want it so it changes the coding for 1 of every 2 lines. So I've came up with this code:
$myFile = "list.txt";
$fh = fopen($myFile, 'r');
$theData = fread($fh, 100);
fclose($fh);
$oldtxt = array("@-", "-@");
$newtxt = array('<li><a href="#">','</a></li>');
$newData = str_replace($oldtxt, $newtxt, $theData);
$array = explode("</li>", trim($newData));
$lineno = count($array);
$linenofinal = $lineno - 1;
for($i=1;$i<$linenofinal;$i++){
if(($i % 2)=='0'){

}
}
The bit that I'm stuck on is inside the if statement. How could I get it to replace for example <li> in line $i with <li class="1in2">

Thanks in advance,

Hi,


I am trying to take a string from a database and replace everything within {} with code... similar to how posting in a forum works.


so say I have "...Lorem ipsom {gallery:1} sit imet..."
it will take that string (from a DB) and replace "{gallery:1}" with "<?php gallery('1'); ?>". How can this be done? Or is there keywords I can search on to find the answer? Thank you in advance.

I'm trying to use preg_replace but I can't get it working.

function replaceContent($sContent)
{
$aReplaceTags = array(
"'\[MENU-CARD\](.*?)\[/MENU-CARD\]'is" => '\\1',
"'\[CONTACT-FORM\]'is" => "Contactform",
);

return preg_replace(array_keys($aReplaceTags), array_values($aReplaceTags), $sContent);
}


This works great however when I change '\\1' into a function the output of '\\1' will always be 1.


function replaceContent($sContent)
{
$aReplaceTags = array(
"'\[MENU-CARD\](.*?)\[/MENU-CARD\]'is" => $this->loadMenuCard('\\1'),
"'\[CONTACT-FORM\]'is" => "Contactform",
);

return preg_replace(array_keys($aReplaceTags), array_values($aReplaceTags), $sContent);
}


Anyone knows what I am doing wrong?

Hi i have this edit form that allows user to mofy data but the problems on the text box is that it deletes the rest of the data after the space from the first word i tried to increase the size of the varChars on mysql but did no work why it happens how can i stop from happening??

this the form input
<input type="text" name="name" id="name"  class='text_box' value="<?php echo $_GET['name'];?>"/>

I'd like to use a text editor like this one: http://tinymce.moxiecode.com/examples/full.php for my forums.


But I am not sure exactly how I would prevent abuse and injects to messed up the page, rather than being contained in  the designated area it is meant for.


Could some   one please help me, I know htmlspecailchars will not work, since some of the code needs to render as html 

I wanted to replace a strings in a large text file .. what would be the fastest way ?!

e.g the text file contains ..

INSERT INTO `subjects` VALUES (1, 'some text here', 'some text here', 'some text here');
INSERT INTO `subjects` VALUES (2, 'some text here', 'some text here', 'some text here');
INSERT INTO `subjects` VALUES (3, 'some text here', 'some text here', 'some text here');
INSERT INTO `subjects` VALUES (4, 'some text here', 'some text here', 'some text here');
INSERT INTO `subjects` VALUES (5, 'some text here', 'some text here', 'some text here');

I wanted to replace the string " VALUES (1, " with  "VALUES (" in each line ..
I'm new in PHP so any response would be much appreciated .. thanks

The title says it all,..well as all u can see, there are many methods to accomplish this done but not before undergoing through a heavy tasking process. For instance,
1. Open the file
2. Reads the content of the file into array.
3. Find out the desire line of text that we want to replace.
4. Make that line of text as variable and assigns with the new data(that we want to replace) as its values.
5.open another file.
6.Write the whole contents to the file opened in 5.
7. Put the contents back to the file of original.

Can anyone contributes a better way to get this done? Like replace/delete a specific line without affecting other characters or anything therein?
Thanx.

P.S
reading and using str_replace to make the alteration always ends up in giving some kind of result beyond desired after the first round of code execution.

Hi all, hope some can help because this is giving me more grey hairs than I allready have.

 

I am trying to solve the following:

I'm pulling in JSON data, decoding it to a array which I write to a database. However in the array are social security numbers that I don't want to store (privacyregulations). So I need to check if a row has a social security number and if it has one I want to replace it with 'anonymized'.

I have got it to work successfully on a local Xampp test environment using the following script (extract off course):

//first anonymize the social security number (ssn) if exists

$data = json_decode($jsondata, true);

foreach($data as &$ssn){
    
            if(!empty($ssn['ssn'])) {
            $ssn['ssn']= '0';$ssn['ssn']= 'anonymized';
            }
    }

// then fill the tables

foreach($data as $row)

{

$insertstatement = mysqli_query($link,"INSERT INTO $tablename (personid, type, ssn) VALUES ('".$row["personid"]."', '".$row["type"]."', '".$row["ssn"]."') ON DUPLICATE KEY UPDATE type = VALUES(type), bsn = VALUES(ssn)");
}

 

This leads to a filled table where the ssn's are filled with 'anonymized' if they exist in the array and empty if it does not exist for that row. This is exactly what I want ;-).

Personid        type    ssn
1                     a    
2                     a        anonymized
3                    b    
4                    a        anonymized

 

However, when I run the same script on a Lamp production environment (lamp stack on an Azure server) it does not work. Then the scripts results in totally ignoring the whole row that contains a ssn??

Personid        type    ssn
1                     a    
3                    b    
 

Hope someone can help to get this working on my production environment as well.

I have taken over a wordpress site that a web developer set up and he is no longer working with me so I cant get his help with it, I have a custom front page that has been pulling press releases that where posted previously and categorized as "press" I was asked to add a blog which I did by categorizing the post as "blog"

In a nutshell, I now need the front page code to pull a mixture of both the "press" and "blog" each category has a numerical id so blog is 7 and press is 3

This is the current code that is in the page
<?php query_posts('category_name=press&showposts=10&offset=0'); ?>

I looked up wordpress support for this, and found this
query_posts(array('category__in' => array(2,6)));

How can I integrate this if possible with the top line so it pulls the newest posts from both categories? Any suggestions could REALLY help me out!

Thanks!

The situation is that I have a large string with some identifiers to say "replace me" with something else. My goal is to replace the values, but if one replacement includes one of the other keys, I don't want to replace it.   For example:

<?php
$str = 'some blob ~abc~ followed by ~def~';

$arr_orig = array(
	'~abc~',
	'~def~'
);

$arr_new  = array(
	'value~def~',
	'blah'
);

echo str_replace( $arr_orig, $arr_new, $str );
?>

This will echo: some blob valueblah followed by blah   But that's not what I'm trying to accomplish. Basically, I want ~abc~ to be replaced with the literal: value~def~ and for the ~def~ that happens to be part of that string to NOT be replaced. I hope what I'm asking is clear. Basically, preg_replace/str_replace with arrays seems no different than just doing a FOR loop and replacing ~abc~ and then ~def~. But that's not what I need.   I'm hoping that if ~abc~ is replaced with text that happens to be another identifier -- ~def~, ~xyz~, whatever -- that this already replaced text is not again replaced. Is there a built-in function to do something like this? If not, should I just parse the whole string and count characters or something? Seems like a pain (and slow!)

Hello,

I am completely new to php so please forgive me ahead of time. I am trying to create a link button on a website for a client that only directs to a certain external website on certain days and hours. Specifically, this is a web radio button that the client only wants to link to the web radio site when their live broadcast is on the air during certain hours on the weekend (i.e. Sundays 8-10 PM). Any other time, the client wants the web radio button to link to a default page since the web radio station plays unrelated music all other hours of the week. Does anyone know the best way to create such a time sensitive link for a button on a webpage?

Thanks.
