I am creating a slideshow editor. I have been able to parse a file and present it to the user in a form. Now I need to figure out how to write the saved information to the file. I want the user to be able to edit the information before and after the slideshow, so there is no specific set of information to be able to overwrite the whole file.
If there is a way to get all of the text before the div and copy it to the variable, add the new information, then get the rest of the information after the div and add that to the variable and then write all that information to the file, then that would work. Otherwise, here is what I have put together.
/* Set Variables */
$x = $_POST['x'];
$file = $_POST['file'];
$path = '../../yardworks/content_pages/' . $file;
$z=0;
while ($z<$x){
$title[$z] = $_POST['image-title'.$z];
$description[$z] = $_POST['image-desc'.$z];
$z++;
}
for ($y=0; $y<$x; $y++){
$contents .= '<li>
<a class="thumb" href="images/garages/'.$file[$y].'">
<img src="images/garages/'.$file[$y].'" alt="'.$title[$y].'" height="100px" width="130px" class="slideshow-img" />
</a>
<div class="caption">
<div class="image-title">'.$file[$y].'</div>
<div class="image-desc">'.$description[$y].'</div>
</div>
</li>';
}
/* Create string of contents */
$mydoc = new DOMDocument('1.0', 'UTF-8');
$mydoc->loadHTMLFile($path);
$mydoc->getElementById("replace")->nodeValue = $contents;
$mydoc->saveHTMLFile($path);
$file = file_get_contents($path);
$file = str_replace("<", "<", $file);
$file = str_replace(">", ">", $file);
file_put_contents($path, $file);
?>
Nothing throws out an error, but the file also remains unchanged. Is there anything I can change or fix to make it write to the file? This is all I have been able to find regarding this specific problem.
I would like to stick to one language, but if I find a way to write to the file using javascript, do the php variables pass on to the javascript section or do I have to stick with one language?
**Edit
Everything is working. ONE problem: is there a way to keep the special characters without converting them? I need the < and > to stay as they are and not convert to a string
I have decided to save the file as it is and use a separate code set to replace the string. I have edited my question above.

Basically, I want to update static HTML files with code snippets input by users from a standard form. I understand how updating the files work, I'm just unsure as to how I go about including the code input from the form to my php file, which is shown below.
<?php
if($handle = opendir()) {
$search = '</body>';
replace = <<< EOF
<!-- I want to populate this with form field input.-->
EOF;
while(false !== ($entry = readdir($handle))) {
if(is_dir($entry)) continue;
$content = file_get_contents($entry);
$content = str_replace($search, $replace . '</body>', $content);
file_put_contents($entry, $content);
}
}
echo 'done';
?>
Any help greatly appreciated.
I would approach this a bit differently. I suggest having a template file aside from the one being modified. That way, you are always modifying a fresh copy instead of having to worry about what changed in the new version.
If your needs become more advanced beyond simply dropping in some markup, I might suggest using a DOM parser.
Finally, I'm sure you have a good reason for writing these static files... just remember the security implications of doing so. You're effectively letting someone do almost anything they want to your server.
Although I agreed it was in no way the best solution to the specific problem, for anyone that may find this useful in the future I used file_get and str_replace to achieve desired results. The code below will allow you to search a file for a specific term and replace with whatever you want based on form input.
<?php
//These are the variables the html file will post to the script.
$filename = $_POST['myFile'];;
$tofind = $_POST['myFind'];;
$toreplace = $_POST['myReplace'];;
$file = file_get_contents($filename);
$end = str_replace($tofind, $toreplace, $file);
$fp = fopen($filename, "w"); //Open the filename and set the mode to Write
if(fwrite($fp, $end)) ; //Write the New data to the opened file
fclose($fp); //Close the File
echo(" File name is $filename ... Finding $tofind .... Replacing with $toreplace ..... Done !");
?>
Though it's a horrible solution, mixed with your code this will do
$replace = array_key_exists('input',$_REQUEST) ? $_REQUEST['input'] : '';
//$replace = sanitize($replace); // there's so much bad with this string
//do the needfull
?>
<form method='GET' action='#'>
<input type='text' name='input' />
<input type='submit' />
</form>
I am saving and editing data in text files through a text area using CKeditor and everything is working smoothly. Everything except new lines ("<br />") that don't show when I try to edit/update the text file via my update.php. I really can't find out what is the issue, I have tried to replace tag after tag and did not manage to solve the problem.
Code for reading and writing on the text file:
$text1 = "../conteudos/start/text1.txt";
if (isset($_POST['body1'])) {
$newData = nl2br($_POST['body1']);
$handle = fopen($text1, "w");
fwrite($handle, $newData);
fclose($handle);
}
// ------------------------------------------------
if (file_exists($text1)) {
$myData1 = file_get_contents($text1);
$myData1 = strip_tags($myData1);
}
Code for editing the text contents:
<textarea class="ckeditor" name="body1" id="body1">
<?php echo str_replace("<br />","",$myData1); ?>
</textarea>
As mentioned before, the text shows up nicely on my index.php with no html tags whatsoever, but when I try to edit it via the text area above I still get no tags, but I get all the text into one single line. This really should be working because I am using "nl2br" function, but apparently something is canceling it.
What can I do?
I think what you are trying to do is:
$text1 = "../conteudos/start/text1.txt";
if (isset($_POST['body1'])) {
$newData = nl2br($_POST['body1']);
$handle = fopen($text1, "w");
fwrite($handle, $newData);
fclose($handle);
}
// ------------------------------------------------
if (file_exists($text1)) {
$myData1 = file_get_contents($text1);
//Change it here first
str_replace("<br />","\n",$myData1); //You also forgot the new line character I think.
$myData1 = strip_tags($myData1);
}
Then you can do this:
<textarea class="ckeditor" name="body1" id="body1">
<?php echo $myData1; ?>
</textarea>
You made a small logic error according to what I see. According to my understanding, you want to strip out the tags but preserve the new line. So change the "< br />" first before you strip out the tags. Hopefully that's what you want I guess.
You are stripping the tags from your file ($myData1 = strip_tags($myData1)). <br /> is a tag, so you're stripping it out too!
This makes your str_replace useless, since the tag has already been stripped. In any case, you shouldn't need that nl2br in the first place, since newline characters are perfectly valid inside text files...
Something very strange happened because according to the user Touch, his method was working on his computer. Unfortunately it wasn't working on mine! So after a while thinking I came to the conclusion that I was over doing some process of replacement of tags. In order to confirm or not this theory of mine I decided do "back-engineer" Touch's method by erasing line by line and seeing what the result was. In the end I saw that my conclusion was correct, I was over doing process of tag replacement because this code:
$text2 = "../conteudos/start/text2.txt";
if (isset($_POST['body2'])) {
$newData = nl2br($_POST['body2']);
$handle = fopen($text2, "w");
fwrite($handle, $newData);
fclose($handle);
}
// ------------------------------------------------
if (file_exists($text2)) {
$myData2 = file_get_contents($text2);
$myData2 = $myData2;
}
worked in perfection. I can only think that this was due to I was using KCEditor...
A big thanks to all that answered, maing me think and helping me this way to achieve my goal!
I have tried to use AJAX, but nothing I come up with seems to work correctly. I am creating a menu editor. I echo part of a file using php and manipulate it using javascript/jquery/ajax (I found the code for that here: http://www.prodevtips.com/2010/03/07/jquery-drag-and-drop-to-sort-tree/). Now I need to get the edited contents of the div (which has an unordered list in it) I am echoing and save it to a variable so I can write it to the file again. I couldn't get that resource's code to work so I'm trying to come up with another solution.
If there is a code I can put into the $("#save").click(function(){ }); part of the javascript file, that would work, but the .post doesn't seem to want to work for me. If there is a way to initiate a php preg_match in an onclick, that would be the easiest.
Any help would be greatly appreciated.
The code to get the file contents.
<button id="save">Save</button>
<div id="printOut"></div>
<?php
$header = file_get_contents('../../../yardworks/content_pages/header.html');
preg_match('/<div id="nav">(.*?)<\/div>/si', $header, $list);
$tree = $list[0];
echo $tree;
?>
The code to process the new div and send to php file.
$("#save").click(function(){
$.post('edit-menu-process.php',
{tree: $('#nav').html()},
function(data){$("#printOut").html(data);}
);
});
Everything is working EXCEPT something about my encoding of the passed data is making it not read as html and just plaintext. How do I turn this back into html?
EDIT: I was able to get this to work correctly. I'll make an attempt to switch this over to DOMDocument.
$path = '../../../yardworks/content_pages/header.html';
$menu = htmlentities(stripslashes(utf8_encode($_POST['tree'])), ENT_QUOTES);
$menu = str_replace("<", "<", $menu);
$menu = str_replace(">", ">", $menu);
$divmenu = '<div id="nav">'.$menu.'</div>';
/* Search for div contents in $menu and save to variable */
preg_match('/<div id="nav">(.*?)<\/div>/si', $divmenu, $newmenu);
$savemenu = $newmenu[0];
/* Get file contents */
$header = file_get_contents($path);
/* Find placeholder div in user content and insert slider contents */
$final = preg_replace('/<div id="nav">(.*?)<\/div>/si', $savemenu, $header);
/* Save content to original file */
file_put_contents($path, $final);
?>
Menu has been saved.
To post the contents of a div with ajax:
$.post('/path/to/php', {
my_html: $('#my_div').html()
}, function(data) {
console.log(data);
});
If that's not what you need, then please post some code with your question. It is very vague.
Also, you mention preg_match and html in the same question. I see where this is going and I don't like it. You can't parse [X]HTML with regex. Use a parser instead. Like this: http://php.net/manual/en/class.domdocument.php
I have created a script which takes a random IMAGE ID from the database, converts it to a valid file name and then I use it to generate random images from a link.
This is how such a link looks like (works - try it):
http://imgit.org/roll.php?image=3J9N0Y4k8g4l4G7
When you reload that link, you'll notice the image changes. If I add this image to <img src="THAT LINK" /> it works, however, it doesn't work on message board like phpBB or vBulletin when I put that link inside [img][/img] BBCode tags.
I suppose there is a problem with my script, because there are various services out there that do exactly the same thing (link on forums) and it works.
Here is my roll.php script:
<?php
$imgit_root_path = '.';
include("{$imgit_root_path}/common.php");
if ($config['disable_roll'])
{
redirect('index.php');
}
$roll_key = request_var('image', '');
$roll_key = substr($roll_key, 0, 15);
if (!$roll_key)
{
redirect('index.php?action=404');
}
if (!$image->roll_key_exists($roll_key))
{
redirect('index.php?action=404');
}
$images = $image->roll_info($roll_key);
$images = explode('|', $images);
$count = sizeof($images);
$index = mt_rand(0, $count - 1);
$extList = array();
$extList['gif'] = 'image/gif';
$extList['jpg'] = 'image/jpeg';
$extList['jpeg'] = 'image/jpeg';
$extList['png'] = 'image/png';
$image_url = generate_site_url() . IMAGES_PATH . $image->get_name($images[$index]);
$image_inf = pathinfo($image_url);
header('Content-type: ' . $extList[$image_inf['extension']]);
readfile($image_url);
?>
I believe the problem may be that phpBB will disallow links which aren't confirmed as images. That is, don't have a known image extension, such as .jpg;
https://www.phpbb.com/community/viewtopic.php?f=46&t=1285255
For security reasons, images whose extensions cannot be confirmed
(such as in the first example) aren't allowed by BBCode. Instead of an
image, it's fully possible for someone to embed a JavaScript script,
or even worse, onto a page which could be a security risk to anyone
visiting the page, or possibly even the server.
This is most likely the same in vBulletin.
Seems you can override it in the forum settings maybe?
Alternatively, if you can change you script, so that you can append a ".jpg" extension to the end, then that may also work!
I think what happens is browser caches image. Try adding header('Cache-Control: max-age=0'); before readfile($image_url);
I need to get all the source values from all image inside a container. I'm having some difficulty with this.
Allow me to explain the process.
All the data comes from a database. Inside the backofficce the user enter all the text and the image inside a textarea. To separate the text with the image the user must enter a pagebreak.
Let's go to the code
while ($rowClients = mysql_fetch_array($rsClients)) {
$result = $rowClients['content'];
$resultExplode = explode('<!-- pagebreak -->', $result);
// with resultExplode[0] I get the code and with resultExplde[1] I get the image
// Now with I want to get only the src value from resultExplode[1]
I already tried with strip_tags
$imageSrc = strip_tags($resultadoExplode[1]);
but it doesn't print anything.
I found this post but without success. I stopped in the first print_r.
Can anyone help me??
Thanks
try foreach, if you can't print it out.. (if that's the problem)
foreach($resultExplode as $key => $value){
echo "[".$key."]".$value;
}
I found a solution:
continuing with the previous code I worked with the split function.
So I start to strip the tags. This way I get the img isolated from the rest.
$image = strip_tags($resultExplode[1],"<img>");
Because all the img has the same structure like this: <img width="111" height="28" alt="alternative text" src="/path/to/the/file.png" title="title of the image">
I split this string, using " as a delimiter
$imgSplit = split('"', $image);
$src = $imgSplit[3];
Voilá. It's working
What do you say about this procedeure??
