PHP - Class To Clean Http Data

Hello, my first post here.

I created a Validation class that depends entirely on static methods. It appears to be working well, but perhaps I misunderstood exactly the purpose and the consequences of using static methods.

My class essentially looks like this:


class Validate
{
static public $errors  = array();
static public $valid   = array();

static public function Name($name)
{
if ($name != '')
{
self::$valid['name'] = $name;
return true;
}
                                else
                                {
                self::$errors['name'] = 'Name is empty';
                return false;
                                 }
}
}


Does this create any chance whatsoever for a collision of data from multiple users? I am beginning to think it does, simply because from what I have recently learned about static methods, theyr'e essentially global variables because they are not instantiated. If that's the case, then it would seem possible that during times of heavy use, any application depending on this class would confuse submitted data.

Any thoughts?

Thanks in advance.

hello dear community, good day,

 

I've been having an issue trying to parse text in a span cass with DOM. Here is my code example. try to extract some lines out of a webpage - with following technique: with the Extraction of values of attributes of elements with DOMDocument. Here is what i have gathered and learned:

 

$remote = "http://website.com/"; $doc = new DOMDocument(); @$doc->loadHTMLFile($remote); $xpath = new DOMXpath($doc); $node = $xpath->query('//span[@class="user"]'); echo $node;

 

and this returns the following

 

error -> "Catchable fatal error: Object of class DOMNodeList could not be converted to string". 

 

And now - with this i need help.

 

What I am trying to do is parse the user name between this tag;

 

<div class="widget plugin-meta"> <h3 class="screen-reader-text">Meta</h3>

 

see more below:Here the concrete example view-source: https://wordpress.org/plugins/participants-database/ and https://wordpress.org/plugins/participants-database/

 

goal  i need the following data:

 

Version: Last updated: Active installations: Tested up:

 

view-source: https://wordpress.org/plugins/participants-database/

 

Proceedings; i checked the source of the webpage. i tried to find out whether the texte is related to some kind of pattern.i have looked closely and found that all of them have

class=”widget plugin-meta”

. Well - This will make extracting them, a piece of cake. I tried with the code below helps to filter html elements based on values of attributes.

but unfortunatley this ends up in a bad result; i need a helping hand and need to know how to parse the above mentioned data

Again; the goal: i need the following data:

Any idea for the starting-point!?  I love to hear from you.

 

Hi...

I have query in highlighting null data using this code:

Code: [Select]
<?php

include 'config.php';

$currentEmpID = $_SESSION['empID']; 
 
 if(!isset($_POST['Regsubmit_'])){ 
     
    $DATE1 = $_GET['Regfirstinput'];
    $DATE2   = $_GET['Regsecondinput'];
 
 $sql = "SELECT DISTINCT IF(ISNULL(a.LOG_IN), 'rdc', '') AS LOGIN_CLASS, IF(ISNULL(a.LOG_OUT), 'rdc', '') AS LOGOUT_CLASS, a.EMP_ID, CONCAT(LASTNAME, ', ' , FIRSTNAME) AS FULLNAME, a.LOG_IN, a.LOG_OUT
 FROM $ATTENDANCE.attendance_build AS a JOIN $ADODB_DB.employment em ON (a.EMP_ID = em.EMP_NO AND em.STATUS IN ('Reg Operatives', 'Reg Staff')) 
 WHERE LOG_IN BETWEEN '$DATE1' AND '$DATE2' 
 OR ISNULL(LOG_IN) OR ISNULL(LOG_OUT)";
 
    $DTR = $conn3->GetAll($sql);
    $smarty->assign('attendance', $DTR);
 }
 $smarty->display('header_att.tpl');
 $smarty->display('RegAttendance.tpl');
 $smarty->display('footer.tpl');
?>

and here is the tpl code:

Code: [Select]
{section name=att loop=$attendance}
  <tr>
    <td colspan="2">{$attendance[att].EMP_ID}</td>
    <td colspan="2">{$attendance[att].FULLNAME}</td> 
    <td colspan="2" class="{$attendance[att].LOGIN_CLASS}">{$attendance[att].LOG_IN|date_format:"%d-%m-%Y %I:%M %p"}</td>
    <td colspan="2" class="{$attendance[att].LOGOUT_CLASS}">{$attendance[att].LOG_OUT|date_format:"%d-%m-%Y %I:%M %p"}</td>
  </tr>
{sectionelse}
  <tr><td colspan="1">No DATA</td></tr>
{/section}

this code highlight the null value of login or logout or both.

this is the css:
Code: [Select]
.rdc {background-color:#ff0000;}

Now, I need to revised my query statement, because i have separate code for adding attendance if the employee has no attendance or no login or no logout.

I just want to happen is if the employee is already add his attendance in NRS table or should I said if the LOG_IN in attendance table is equal to TIME_IN in NRS table the data will have a color yellow.

For Example:

I have this data in attendance table:

EMP_ID = 012012
LOG_IN = NULL
LOG_OUT = 2011-12-12 13:35:00

I will his attendance in NRS table to have his attendance:

EMP_NO = 012012
TIME_IN = 2011-12-12 05:35:00
TIME_OUT = 2011-12-12 13:35:00



In my above query the LOG_IN has a background color of RED.

I want to happen is if I add his attendance in NRS the EMP_NO, LOG_IN, LOGOUT will have a color to notice that it is already have in NRS.

Because theirs a scenario that the employee has no login or no logout or both.


Feel free to ask me if my explanation is not clear to you.

Thank you in advance

I need to set up a threaded comments system in a PHP project and I got this script shown below from http://www.jongales....#comment-436261

class Threaded_comments
{
    
    public $parents  = array();
    public $children = array();

    /**
     * @param array $comments 
     */
    function __construct($comments)
    {
        foreach ($comments as $comment)
        {
            if ($comment['parent_id'] === NULL)
            {
                $this->parents[$comment['id']][] = $comment;
            }
            else
            {
                $this->children[$comment['parent_id']][] = $comment;
            }
        }        
    }
   
    /**
     * @param array $comment
     * @param int $depth 
     */
    private function format_comment($comment, $depth)
    {   
        for ($depth; $depth > 0; $depth--)
        {
            echo "\t";
        }
        
        echo $comment['text'];
        echo "\n";
    }
    
    /**
     * @param array $comment
     * @param int $depth 
     */ 
    private function print_parent($comment, $depth = 0)
    {   
        foreach ($comment as $c)
        {
            $this->format_comment($c, $depth);

            if (isset($this->children[$c['id']]))
            {
                $this->print_parent($this->children[$c['id']], $depth + 1);
            }
        }
    }

    public function print_comments()
    {
        foreach ($this->parents as $c)
        {
            $this->print_parent($c);
        }
    }
  
}

Here’s the example usage with the data provided as an array:

$comments = array(  array('id'=>1, 'parent_id'=>NULL,   'text'=>'Parent'),
                    array('id'=>2, 'parent_id'=>1,      'text'=>'Child'),
                    array('id'=>3, 'parent_id'=>2,      'text'=>'Child Third level'),
                    array('id'=>4, 'parent_id'=>NULL,   'text'=>'Second Parent'),
                    array('id'=>5, 'parent_id'=>4,   'text'=>'Second Child')
                );

$threaded_comments = new Threaded_comments($comments);

$threaded_comments->print_comments();

I have a sample select query that pulls data from a database and stores the result in the $comments array as shown below. The $comments array is then passed as an argument to the $threaded_comments object:

$sql = 'SELECT * FROM test_comments';
// submit the query and capture the result
$result = $conn->query($sql);
$comments = array();
while ($row = $result->fetch_assoc()) {
    $comments[] = $row;
}

The challenge is that nothing is printed to the screen when I run the script. Inspection of the comments array with the var_dump function is shown below:

array (size=4)
  0 => 
    array (size=3)
      'id' => string '1' (length=1)
      'parent_id' => string '0' (length=1)
      'text' => string 'comment' (length=7)
  1 => 
    array (size=3)
      'id' => string '2' (length=1)
      'parent_id' => string '0' (length=1)
      'text' => string 'comment' (length=7)
  2 => 
    array (size=3)
      'id' => string '3' (length=1)
      'parent_id' => string '1' (length=1)
      'text' => string 'comment ' (length=8)
  3 => 
    array (size=3)
      'id' => string '4' (length=1)
      'parent_id' => string '3' (length=1)
      'text' => string 'comment ' (length=8)

I was wondering if the array format from my select query is the issue? Could anyone provide a clue as to how to fix this?   Thanks.

What is the cleanest way to write this if?

Code: [Select]
<div <?php if (!empty($otherfans)) {echo "class=\"newstext\"";} else {echo "class=\"newstext pts\""; } ?>>

My code here

Code: [Select]
  setcookie('hide_div', $_COOKIE['hide_div'].','.$_GET['hide'],time()+32000000);
When I set it, it works wonderful, but then when I see view it in my cookie it shows this code between my $_GET['hide'] values

Code: [Select]
%2C
how do I clean it up and just make it show my " , "?

Thank you

Hi,

Here is a tiny bit of my code


$r = mysql_query ($query);

while ($row = mysql_fetch_array ($r, MYSQL_ASSOC)) {
 


echo "<tr>

<td align=\"center\">";  echo date("M-d-Y", mktime(0, 0, 0, $row['month'], $row['day'], $row['year'])); echo "</td> ";

    if ($row['presenter1status'] == '0')
              {
              echo "<td align=\"center\"><font color=\"#FF9900\">{$row['presenter1']}</font></td>";
              }
          elseif ($row['presenter1status'] == '1')
              {
              echo "<td align=\"center\"><font color=\"green\">{$row['presenter1']}</font></td>";
              }
          elseif ($row['presenter1status'] == '2')
              {
              echo "<td align=\"center\"><font color=\"red\">{$row['presenter1']}</font></td>";
              }


    if ($row['presenter2status'] == '0')
              {
              echo "<td align=\"center\"><font color=\"#FF9900\">{$row['presenter2']}</font></td>";
              }
          elseif ($row['presenter2status'] == '1')
              {
              echo "<td align=\"center\"><font color=\"green\">{$row['presenter2']}</font></td>";
              }
          elseif ($row['presenter2status'] == '2')
              {
              echo "<td align=\"center\"><font color=\"red\">{$row['presenter2']}</font></td>";
              }
            
            
             if ($row['engineerstatus'] == '0')
              {
              echo "<td align=\"center\"><font color=\"#FF9900\">{$row['engineer']}</font></td>";
              }
          elseif ($row['engineerstatus'] == '1')
              {
              echo "<td align=\"center\"><font color=\"green\">{$row['engineer']}</font></td>";
              }
          elseif ($row['engineerstatus'] == '2')
              {
              echo "<td align=\"center\"><font color=\"red\">{$row['engineer']}</font></td>";
              }
            
echo "</tr>


I was wondering if there is a better way of doing this as I think including this many ifesle statements in a while loop that could go round about 40 times might be very heavy on the resources.

Thanks

Hey guys

 I have a lot of inputs from my form. Is there a way I can do like a for each or something instead of of having to write

$myusername = stripslashes($_POST['name');
$mypassword = stripslashes($_POST['pass']);
$myusername = mysql_real_escape_string($myusername);
$mypassword = mysql_real_escape_string($mypassword);

.... for all 16 fields?

thanks

How do I only redirect the page when index.php is present?

Hi

Im trying to write a script to clean up my image directory which has quite a lot of unused images that have built up over time.
In order to do this I am doing the following.

First Create a database table called 'image_clean' Then I'm searching through 3 tables and collecting all the image file names and dumping the names in the table 'image_clean'

Can do that no problem. So now I have all the images I need in this one table 'image_clean' I now want to go through my directory 'image_uploads' and delete anything thats not in the 'image_clean' table.

I know how to delete the files using unlink Im just unsure how to search through the directory file by file and check the file against the database. Im asumming I need to put them in an array. Could anyone give be a clue or two to get me started.

I have no problem checking a database against a directory but when its the other way round 'checking a directory against a database I'm lost. What I might do is pop the files to delete in a new database called 'image_delete' so that I can then check the images to delete before I write the unlink script. But I'm just not sure how to pick up each file and compare it to the table.

Thanks in advance.

Hi,

I am creating a website but am having trouble with the following:

I have an include file(db.inc) which contains the following:

function clean($input, $maxlength)
{
$input = substr($input, 0, $maxlength);
$input = EscapeShellCmd($input);
return ($input);
}

The file I am having the problem with is my view.php file. I get the following error:

Notice: Undefined variable: file in C:\wamp\www\fermpix\view.php on line 4

Line 4 contains the following:

$file = clean($file, 4);

My view.php does have the line:

include 'db.inc';


Does anybody have any idea what the issue might be?

Cheers
Paul

I've been messing around with clean urls in php and I've been having some trouble. I'm working on a private messaging system and when I go to "sitename.com/mail/view.php?page=inbox" it correctly displays the users inbox messages but when I put "sitename.com/mail/view/inbox/" it just displays the page like the GET value isn't set. Why is that?

this is the HTACCESS file for clean url

RewriteEngine on

RewriteCond %{REQUEST_FILENAME} !-d

RewriteCond %{REQUEST_FILENAME}\.php -f

RewriteRule ^view/([a-z]) view.php?page=$1 [NC,L]

 

I created a new homepage for my network of sites I run. I tried to go for a simple and clean look. The pages themselves function how I'd like, but I'm unsure if the menu system is easy to understand or not.   I even added a time limited message on the front page of the site indicating that the logo was clickable, but purposely left it off of other sub-pages to try and keep the design as clean as possible.   Check it out, let me know what you think.   http://ctenetwork.com
