PHP - Can't Figure Out Why Recursive Replace Is Not Working

I've tried a few different methods, but I can't get this damn function to work. Can someone show me where I've gone wrong?

Here's my code & form. I'm still baffled why it doesn't work! :lol:

url is update-content.php?id=12


<?php
    include("../include/session.php");
      
      if(!$session->logged_in)
      {   
          header('Location: ../login.php');
          die; 
      } 
    require_once('../include/functions.php');
    


    function content($id)
    {    
        $id = $_GET['id'];
        $connection = db_connect();            
        $query = sprintf("select * from content where id = '$id'",                                     
                                     mysql_real_escape_string($id)                                
                                     ); 
            
            $result = mysql_query($query);                
            $number_of_posts = mysql_num_rows($result);
            if ($number_of_posts == 0) 
            {
              return false;    
            }            
            $row = mysql_fetch_array($result);            
            return $row;            
    }

function update($param)
{
     // Get the content id from url to output into the editor    
     $id = $_GET['id'];
     $connect = db_connect();
    
            $page = mysql_real_escape_string($_POST['page']);
            $page_id = mysql_real_escape_string($_POST['page_id']);
            $title = mysql_real_escape_string($_POST['title']);
            $text = mysql_real_escape_string($_POST['text']);   
                    
            $query = ("UPDATE content SET
                                                page = '$page'
                                                page_id = '$page_id'
                                                title = '$title'
                                                text = '$text'
                                             WHERE id = '$id'
                                             ");
             $result = mysql_query($query); 
    
            if (!$result) {
                return false;
            } else {
                return true;
            }                           
}  

?>

<?php
        // Send form data to mysql    
        if(isset($_POST['text']))
        {
            $result = update($_POST);
            if($result === true)
            {
                echo 'Success!';
                die();
            }
        }
        
?> 



And the form..

 <form form name="editor" id="editor" method="post"  action="update-content.php">
  <p><br />
        <b>Assign to page</b><br />
          <input name="page" id="page" size="60" maxlength="500" value="<?php $page = content($id);  echo stripslashes($page['page']); ?>" />

          <br />                                                
    
    <b>Title</b>
           <span class="smalltext">(Just a short name this piece of content)</span><br />

      <strong>Content</strong> <span class="smalltext">(paste html in here)</span><br />
      <textarea name="text" id="text" cols="75" rows="15"><?php $text = content($id); echo stripslashes($text['text']); ?></textarea>
      <?php //turn the text area into CK Editor  echo $ckeditor_ini; ?>
          <br />
          <input type="image" src="../images/button_submit.gif" alt="submit" name="submit" value="submit" />

    </form> 

Wordpress gave me the following error when uploading the this themeforest theme. 

failed opening '/srv/htdocs/wp-content/themes/QuickFixWebiste(Wordpress)/../../../wp-admin/includes/class-walker-nav-menu-edit.php' for inclusion (include_path='.:/usr/local/php7.2/lib/php') in /srv/htdocs/wp-content/themes/QuickFixWebiste(Wordpress)/library/core/admin/edit-menu-walker.php

Can anyone tell me how to resolve this?

The source code in the edit-menu-walker.php on lines 1-4 is:

<?php
if (!class_exists('Walker_Nav_Menu_Edit')){
	include_once(get_template_directory() . '/../../../wp-admin/includes/class-walker-nav-menu-edit.php');
}

 

Code: [Select]
$text = preg_replace('{-(\d+)}e', '-convertNumber("$1")', $text);
i have strings im trying to replace like this:

name-2 > name-two
name-p2 > name-p2

im trying to match and replace the first one and basically ignore the second one. ive included the hyphen in the code. so why isnt this working?

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!)

Something bothers me:
I am writing a PHP code to implement "step by step" form. In order to do that, I copied a method which looks like:

Program name: doit.php :

if (!isset($_SESSION['para_stage'])) { ... first time to the code .... initialize variables ...display first form which calls doit.php when submit.....}
else {already been to this code, variables are initialized, do what you have to do and recall doit.php ....}

It works fine, but: isn't there a problem with calling the same program again and again from itself? isn;t it like a recursive, which means the stack will be used until overflow?

Hi
i wrote a find and replace code but my code replace last value of array and skip the first, second.... values in the array.
Please give me an idea because i stack with this code.

Regards

Hello!
Maybe I'm a bit ashamed to question some little kind of thing, but I tested 3 hours and couldn't let this function. It's like the most easiest possible recursiv function...:

Code: [Select]
function recursiv($s){
  $s.="b";
  if(strlen($s)>30){return $s;}
  //else return 0;
  else recursiv($s);
}
echo recursiv("h");

The result is a blank page...

Thanks a lot for your help !!

Code: [Select]
        public function getBonusChildren($userID)
        {
if($userID != NULL)
{
$sql = 'SELECT COUNT(*) AS count, userID FROM jos_backoffice_users WHERE parentID= ' . $userID . ';';
$stmt = conn::getInstance()->prepare($sql);
$stmt->execute();
                $obj = $stmt->fetchAll(PDO::FETCH_ASSOC);
if(is_object($obj))
{
$obj->count += $this->getBonusChildren($obj->userID);
}
}
                return $obj->count;
}
I get no error.  It just always return null.   How can I get this done?

I'm really fond of your coding and need some help too I'm also trying to make a tree and save it in an xml file such that parent_id of one node is inserted in as pages key to the father node.By running this query
$sql = "Select * from category order by parent_id ASC";
I'm getting the following result.
Array
(
    => Array
        (
            [category_id] => 2
            [parent_id] => 0
            [category_name] => Clothes
        )

    [1] => Array
        (
            [category_id] => 5
            [parent_id] => 1
            [category_name] => T-shirts
        )

    [2] => Array
        (
            [category_id] => 6
            [parent_id] => 1
            [category_name] => Cotton-Shirts
        )

    [3] => Array
        (
            [category_id] => 1
            [parent_id] => 2
            [category_name] => Upper
        )

    [4] => Array
        (
            [category_id] => 4
            [parent_id] => 2
            [category_name] => Lower
        )

    [5] => Array
        (
            [category_id] => 3
            [parent_id] => 4
            [category_name] => Pants
        )

)
 
My code is as follows but not executing correctly
function searchTree($arr,$node,$i){
      if(!in_array($node['parent_id'],$arr[$i])) {
         $stmt =  '<pages_'.$i.'>';
         $stmt .=$node;
         $stmt .='</pages_'.$i.'>';
         return $stmt;}
      else{
         //print_r($returnTree);
         print_r ($arr[$i]);//['category_id'];
         $returnTree = ($arr[$i]['category_id']==$node['parent_id'])?
          searchTree($arr,$node,$i++): searchTree($arr,'',$i++);
      }
}
   $i=0;
   foreach($links as $link){
$myArr = searchTree($links,$link,$i);}

The result should be as follows:
<page_1>
        <label>Clothes</label>
        <uri>#</uri>
<pages>

        <page_1_1>
                   <label>Upper</label>
                   <uri>#</uri>
                   <pages>
                              <label>T-Shirt</label>
                              <uri>#</uri>
                              <page_1_1>
                                    <page_1_1_1>
<label>Short Sleaves</label>
<uri>#</uri>
</page_1_1_1>
<page_1_1_2><label>Long Sleaves</label><uri>#</uri>
</page_1_1_2></page_1_1></page_1>
<page_1_2>
                   <label>Lower</label>
                   <uri>#</uri>
                   <pages>....</page_1_2>

Hopefully you can unsderstand this problem. Please help me.

Hello,   Here is my code:

I am looking to index a large amount of documents using elastic search and php. I have a very complex directory filled with other directories that i need to index into an array. I wanted to see if my code looked right, and if not what am I doing wrong?    Thanks, Austin Harmon

Hi,

I am using a separate class for all the functions. And using using the following function "objectToArray" to convert the JSON decoded object to Array.

Class file:
       

               class xyz
              {
                    . 
                    .
                    .
                    .
                    .

                    function objectToArray($d) {
         if (is_object($d)) {
       $d = get_object_vars($d);
                  }
         if (is_array($d)) {
     return array_map(__FUNCTION__, $d);
         }
         else {
     return $d;
         }
          }
                    .
                    .
                    .

          }
      


Main page:

          $obj = new xyz();

          $arr = $obj->objectToArray($json_obj);



Because the function "objectToArray" is recursive, array_map(__FUNCTION__, $d) is not able to applies the callback. And throws the warning "array_map() expects parameter 1 to be a valid callback".

Need help!

Girish

i have the below script but it doesn't work it just refreshes the page anyone know what is wrong

Code: [Select]
<?php
$path = "../../gallery/gallery_files/gallery/";
if(isset($_POST['file']) && is_array($_POST['file']))
{
foreach($_POST['file'] as $file)
{

$dirname = $path; 

//Recursive Delete Function

function DELETE_RECURSIVE_DIRS($dirname)
{ // recursive function to delete
  // all subdirectories and contents: 
  if(is_dir($dirname))$dir_handle=opendir($dirname); 
  while($file=readdir($dir_handle)) 
  {                                                      
    if($file!="." && $file!="..") 
    { 
      if(!is_dir($dirname."/".$file))unlink ($dirname."/".$file); 
      else DELETE_RECURSIVE_DIRS($dirname."/".$file); 
    } 
  } 
  closedir($dir_handle); 
  rmdir($dirname); 
  return true; 
}

}
}

Hi there,

I have written a recursive function that basically generates a tree structure for my site pages (kind of like a sitemap). It all worked fine until yesterday, I started getting error messages telling me that I have exhausted the amount of memory available.

There are only about 30 pages in the site (parent, child, sub-child etc), so I dont think that I should be using up that much memory. This was my first attempt at a recursive function so I am pretty sure that it may not have been optimised properly.

If anyone could take a look and offer any feed back that would be great. (written in codeigniter framework)

       function getAllPages() {
      
      $this->tmp_arr = array();
      
      $this->buildPageStructure(0, 0);
      
      return $this->tmp_arr;
      
   }
   
   
   
   function buildPageStructure($parent_id, $counter) {
   
      $CI = & get_instance();
      
      $query = $CI->db->query("SELECT page_id, title, page_url, status FROM pages WHERE parent_page='$parent_id' ORDER BY sort_order ASC");
      
      $counter++;
      
      if($query->num_rows() > 0) {
      
         foreach($query->result() as $row) {
            
            $new_arr = new Page();
            
            $new_arr->page_id = $row->page_id;
            $new_arr->title = $row->title;
            $new_arr->level = $counter;
            $new_arr->page_url = $row->page_url;
            $new_arr->status = $row->status;
            
            $this->tmp_arr[] = $new_arr;
                        
            $this->buildPageStructure($row->page_id, $counter);            
            
                     
         }
         

      }
   
   }

Dear all,

Hello, i'm a newbie programmer. I want to implement the concept about recursive descent parser for natural language (english). The concept was found in http://nltk.sourceforge.net/doc/en/ch07.html#rdparser. But my problem is, how to implementation the concept/theory to PHP code ? Anyone would to help me to give the advice or tutorial or maybe anyone has to make script before?

Thank you very much in advance.

If i have a list of categories like:
1. Billboards and advertisement section
  1(a)City Clock
    1(a)(i)Application fee  (has columns for approved price and proposed price)
    1(a)(ii)Advertisement Per year (has columns for approved price and proposed price)

  1(b)Billboards
    1(b)(i)Application fee for construction (has columns for approved price and proposed price)
    1(b)(ii)Charge per year without advertisement (has columns for approved price and proposed price)

  1(c)Something here.....
    1(c)(i) something here...(has columns for approved price and proposed price)
    1(c)(ii)something here...(has columns for approved price and proposed price)
    1(c)(iii) something here... (has columns for approved price and proposed price)
     e.t.c

THEN SOME CATEGORIES LOOK LIKE:category 2
2. Category name
  2(a)something here..(has columns for approved price and proposed price)
  2(b)something here..
    2(b)(i)something here..(has columns for approved price and proposed price)
    2(b)(ii)something here..(has columns for approved price and proposed price)



NOW: i have categories without sub categories and others with sub-sub categories , a main category doesn't does have a column for prices ( or lets just say other columns) , a sub category WITHOUT its sub category will have columns for prices, if a sub category has its sub category, then its subcategory should have columns for prices (this is where my problem is - how do i handle such a situation in php Mysql?? )
