PHP - Simple Eval Question
Basically I am making a class which displays a set of data.
Now sometimes the data returned from the database will be a unix time stamp so this needs to be displayed in a correct form. For this I use str_replace $replace - below this will contain a way of converting the data Replace is defined by: $replace = 'date(\'d-m-y\',$row_data[\'lastupdate\'])'; $row.= str_replace('{data}',eval($replace),'<td>{data}</td>'); This just gives me Parse error: syntax error, unexpected $end in C:\xampp\htdocs\z\src\lib\lib.table.php(348) : eval()'d code on line 1 Is this possible at all? Similar TutorialsWell from the fantastic response on my last post (0 replies, 80+ views), I've decided to browse A LOT of articles on how to do what I need to do. And, well I got it down to the function in PHP as Eval. I have my code set up like this: Code: [Select] $query="SELECT * FROM info"; $results = mysql_query($query); while ($row = mysql_fetch_assoc($results)) { $x = $row['pointtext']; echo $x; } As you can see this, this is a simple query to grab all the rows under pointtxt. I have only 1 at the moment which is to text it, and it echo's it fine! It echo's this: Code: [Select] Imagettftext($im, 12, 0, $start_x, $start_y, $black, 'verdana.ttf', "text to write"); This is a PHP script for TEXT-TO-IMAGE. SO then considering the echo worked, I used this code: Code: [Select] $query="SELECT * FROM info"; $results = mysql_query($query); while ($row = mysql_fetch_assoc($results)) { $x = $row['pointtext']; header("Content-Type: image/jpeg"); $im = ImageCreateFromPng("test.png"); $black = ImageColorAllocate($im, 255, 255, 255); $start_x = 10; $start_y = 20; eval($x); Imagejpeg($im, '', 100); ImageDestroy($im); } And as you can imagine, it doesn't work. As I said in my 2 day old topic, I want it to have the ability to put more text onto the image and save it. So, do I get help this time? PLEASE. Does the eval function not support the TEXT TO IMAGE got an error in the script. What, please at least answer this time. _______ Also forgot to mention that how the script doesn't work, is it displays the picture fine, but it doesn't place any text onto it. Or any I can see with the set coords. Hello there, I have a issue. My issue is that I parse PHP code executed by people via a command like so !php echo("hello there"); would output "hello there". Here is my command: case ':!php': $message = ""; for($i=4; $i <= (count($this->ex)); $i++) { $message .= $this->ex[$i]." "; } ob_start(); @eval($message); $output = ob_get_contents(); fputs($this->socket,"PRIVMSG #volt :{$output}\r\n"); ob_end_flush(); break; $message contains the code to be executed. But the problem is it won't return more than one line. I really want it to be able to output multiple lights from eval E.G if someone where to output a item that is split up into multiple lines. Does anybody know how to accomplish this? im got php code witch is there Code: [Select] <?php /* Hello World (helloworld.php) */ //Required for Active Members / Last 24 Active Members Plugins define('SCRIPTNAME', 'test.php'); //Load templates for this page to avoid extra usage of SQL queries. $LoadTemplatelist = array('test'); //Init require('./library/init/init.php'); //Set Page Title $Page_Title = get_phrase('test'); //Create & Add Breadcrumb AddBreadcrumb(array ( get_phrase('navigation_home') => $TSUE['TSUE_Settings']->settings['global_settings']['website_url'].'/?p=home&pid=1', get_phrase('test_home') => $TSUE['TSUE_Settings']->settings['global_settings']['website_url'].'/?p=test&pid='.PAGEID )); //Get Page Template $test = ''; $query = mysqli_connect(MYSQL_HOST, MYSQL_USER, MYSQL_PASS, MYSQL_DB); $sql = mysqli_query($query, "SELECT `filename`, `tid`, `info_hash`, `name`, `description`, `cid`, `size`, `added`, `leechers`, `seeders`, `times_completed`, `owner`, `options`, `nfo`, `sticky`, `flags`, `mtime`, `ctime`, `download_multiplier`, `upload_multiplier` FROM `tsue_torrents`, `tsue_attachments` WHERE `content_type`='torrent_images' AND `content_id` = `tid` LIMIT 0, 10"); while ($row = mysqli_fetch_array($sql)) { $test_row = ''; $description= $row['description']; $name= $row['name']; $leechers= $row['leechers']; $owner= $row['owner']; $filename= $row['filename']; $nunx= $row['tid']; $seeders= $row['seeders']; eval("\$test_row = \"".$TSUE['TSUE_Template']->LoadTemplate('test_row')."\";"); $test .= $test_row; } eval("\$test = \"".$TSUE['TSUE_Template']->LoadTemplate('test')."\";"); //Print HTML Output PrintOutput($test, $Page_Title); ?> any chance to call that code to other template?

Im trying to put if and else condition on my php code. However this condition is not working.. Code: [Select] if($file == #3#){ echo "No results found"; }else{ echo "results has been found"; } This variable $file is the result after i used an API.. If the API does not see any results they would return #3# as the result. This means they returned a transaction code of 3 which you can see here http://developer.textapp.net/WebService/TransactionCodes.aspx means that there was nothing to return. The condition does not function well even if i make 3 or #3# as part of the condition. Can you help me guys? thanks Hello everyone! I am a new user and I have a simple question. How do I set a password for a user to log in to my site with PHP? I have no MySQL database just a iOS code/host app. I know this isn’t secure but only me and my friends are on the site. Any help is appreciated. what does the # symbol do in php(e.x index.php?cat=1#privacy)? How can i use it? From what i 've seen you use it for changing a whole div without reloading the page like tabs.. I've seen this, Code: [Select] <?php } ?> in a lot of scripts at the very end of the script. What does this piece of code do? Lets say I have: $var=5; What would an output look like to get me: 1<br> 2<br> 3<br> 4<br> 5<br> Im at a complete loss! Thanks! Hey! I have a drop down field for my "register" form, but this is clearly easy to edit, I just used tamperdata for firefox and yeah...pretty easy, is there any way that you could prevent tampering with the values when submitting this form!? Hello there fellow programmers, I was just wondering if there was any difference between doing this: Code: [Select] echo "Say Something Here"; and this Code: [Select] echo "Say "; echo "Something "; echo "Here"; Thank you in advance. Notice: I am aware of the fact that they will output the same thing, my question is regarding resources. if someone can help me out with this, its quite simple but I can't seem to get it to work.. Basically, this is the code I have for now, the issue is if I have 0 product or items, I don't want the sorting option to show up on the page, from the code below, what line can I add tosay that if there is no products in a category, not to show the SORT feature. thanks in advance if anyone can help. {if isset($orderby) AND isset($orderway)} <!-- Sort products --> {if isset($smarty.get.id_category) && $smarty.get.id_category} {assign var='request' value=$link->getPaginationLink('category', $category, false, true)} {elseif isset($smarty.get.id_manufacturer) && $smarty.get.id_manufacturer} {assign var='request' value=$link->getPaginationLink('manufacturer', $manufacturer, false, true)} {elseif isset($smarty.get.id_supplier) && $smarty.get.id_supplier} {assign var='request' value=$link->getPaginationLink('supplier', $supplier, false, true)} {else} {assign var='request' value=$link->getPaginationLink(false, false, false, true)} {/if} <form id="productsSortForm" action="{$request|escape:'htmlall':'UTF-8'}"> <select id="selectPrductSort" onchange="document.location.href = $(this).val();"> <option value="{$link->addSortDetails($request, $orderbydefault, $orderwaydefault)|escape:'htmlall':'UTF-8'}" {if $orderby eq $orderbydefault}selected="selected"{/if}>{l s='--'}</option> {if !$PS_CATALOG_MODE} <option value="{$link->addSortDetails($request, 'price', 'asc')|escape:'htmlall':'UTF-8'}" {if $orderby eq 'price' AND $orderway eq 'asc'}selected="selected"{/if}>{l s='Price: lowest first'}</option> <option value="{$link->addSortDetails($request, 'price', 'desc')|escape:'htmlall':'UTF-8'}" {if $orderby eq 'price' AND $orderway eq 'desc'}selected="selected"{/if}>{l s='Price: highest first'}</option> {/if} <option value="{$link->addSortDetails($request, 'name', 'asc')|escape:'htmlall':'UTF-8'}" {if $orderby eq 'name' AND $orderway eq 'asc'}selected="selected"{/if}>{l s='Product Name: A to Z'}</option> <option value="{$link->addSortDetails($request, 'name', 'desc')|escape:'htmlall':'UTF-8'}" {if $orderby eq 'name' AND $orderway eq 'desc'}selected="selected"{/if}>{l s='Product Name: Z to A'}</option> {if !$PS_CATALOG_MODE} <option value="{$link->addSortDetails($request, 'quantity', 'desc')|escape:'htmlall':'UTF-8'}" {if $orderby eq 'quantity' AND $orderway eq 'desc'}selected="selected"{/if}>{l s='In-stock first'}</option> {/if} </select> <label for="selectPrductSort">{l s='Sort by'}</label> </form> <!-- /Sort products --> {/if} I can't figure out why im getting an error with this code. if ($notif = mysql_query("SELECT * FROM notifications_1 WHERE recieverid='". $_SESSION['id']."' ORDER BY read ASC, id DESC") or die (mysql_error())); { Code: [Select] You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'read ASC, id DESC' at line 1 I'm teaching myself php and mysql -- and my coding is a little rough. But what i'm trying to do is display information from a mysql table in another table on a website. I can do this just fine simply displaying the table, but i want a little something different. I am only displaying one column of the table, instead of displaying it all in one column, i want to display the information in 5 columns. for example..... the table from mysql has names scott, john, james, mary, simon. with the code I have i can make it display like this: scott scott scott scott scott john john john john john james james james james james mary mary mary mary mary simon simon simon simon simon i want it to diplay like this: scott john james mary simon new names will continue down here is my code: <?php require ("connectigb.php"); $result = mysql_query ("SELECT pledgeName FROM pledgewall"); $fields_num = mysql_num_fields($result); echo "<center> <h1>TSA It Gets Better Pledge Wall</h1>"; echo "<table border='1' align='center' style='width:960px;'><tr>"; while($row = mysql_fetch_row($result)) { echo "<tr>"; // $row is array... foreach( .. ) puts every element // of $row to $cell variable foreach($row as $cell) if ($cell != "") { for ($j=0; $j<5; $j++) { echo "<td>$cell</td>"; } } echo "</tr>\n"; } mysql_free_result($result); echo "</table></center>"; ?> any ideas on what i can do here, i'm sure this is a simply fix. i just haven't come across it yet. thanks for the help in advance.
