PHP - Variable String Syntax
Similar TutorialsHi, I am trying to make some adjustments to uploadify.php which comes with the latest version of uploadify (3.0 beta), so that it works with a session variable that stores the login username and adds it to the path for uploads. Here is uploadify.php as it currently looks: Code: [Select] <?php session_name("MyLogin"); session_start(); $targetFolder = '/songs/' . $_SESSION['name']; // Relative to the root if (!empty($_FILES)) { $tempFile = $_FILES['Filedata']['tmp_name']; $targetPath = $_SERVER['DOCUMENT_ROOT'] . $targetFolder; $targetFile = rtrim($targetPath,'/') .'/'. $_FILES['Filedata']['name']; // Validate the file type $fileTypes = array('m4a','mp3','flac','ogg'); // File extensions $fileParts = pathinfo($_FILES['Filedata']['name']); if (in_array($fileParts['extension'],$fileTypes)) { move_uploaded_file($tempFile,$targetFile); echo '1'; } else { echo 'Invalid file type.'; } } echo $targetFolder; ?> I added Code: [Select] echo $targetFolder; at the bottom so that I could make sure that the string returned was correct, and it is, i.e. '/songs/nick'. For some reason though, uploads are not going to the correct folder, i.e. the username folder, but instead are going to the parent folder 'songs'. The folder for username exists, with correct permissions, and when I manually enter Code: [Select] $targetFolder = '/songs/nick';all works fine. Which strikes me as rather strange. I have limited experience of using php, but wonder how if the correct string is returned by the session variable, the upload works differently than with the manually entered string. Any help would be much appreciated. It's the last issue with a website that was due to go live 2 days ago! Thanks, Nick Hello,
L.marker([{{$adLocation->lat}}, {{ $adLocation->lng }}]).addTo(locationMap)

{
return str_replace( array("\r\n", "\r", "\n"), "<br />", $s);
// 2 lines below does not work too
// return preg_replace('/\<br(\s*)?\/?\>/i', "\n", $s);
// return nl2br($s);

edit:539 Uncaught SyntaxError: Invalid or unexpected token
Have a ton of pop-up javascript links in my page. To tidy up the code, I have decided to declare all links at top of the page to keep them together and simply use the variable within the "a" brackets. Let me show you: Code: [Select] <? $brand_edit = 'javascript:void(0)"onclick="window.open('/admin/form.php?db=outlet&tbl=brands&auto_increment=<? echo $auto_increment; ?>&action=edtamp;step=1','none','width=750,height=250,menubar=no,status=no,resizable=no,location=no,toolbar=no,scrollbars=yes,left=50,top=50,titlebar=no')'; ?> <span class="float" style="width: 100px;"><a href="<? echo $brand_edit; ?>"><? echo $auto_increment; ?></a></span> However, something things to go wrong as I'm getting an "Parse error: syntax error, unexpected '=' in ... on line 12" Where am I going wrong with my syntax? What's the correct syntax for having a variable in a select statement? Here's an example of what I'm trying to do (after I'm already connected to the database). Code: [Select] $username = "thomas"; $query = mysql_query( "SELECT * from users WHERE username = $thomas" ); if( mysql_num_rows( $query ) > 0 ) { bla bla... It works if I don't put the WHERE part in, but I get an error if I use it, so I'm assuming I have the wrong syntax for using a variable in the select statement. I have a query: $query ="select * FROM telephone_admin where name Like ' ".$_GET['answer']." ' "; I would like to add % before and after so that the query will search for result which contains the PHP variable $_GET['answer'] before or after, but the problem is how can I add % before or after ' ".$_GET['answer']." ' within the query?? Thanks! Hey all, Let's say I want to do something like this: Code: [Select] <?php function exists($a){ $b ||= $a; } echo exists(1); ?> Basically, every time exists is called, it will only assign b to a if b isn't already initialized. What's the most effective way to achieve the equivalent in php? ternary? Thanks for response.

I have a PHP script that I have run into a problem on. The basic idea of the script is that it will send out HTML formatted emails to users of my web site. The problem I am running into is storing the HTML content in memory so I can do a str_replace() looking for certain markers in the HTML and replace them with lets say the users name and custom links that pertain to the particular user that the email is going to. Currently the HTML is being stored in a MySQL database, but I have already tried reading it from a flat file. Each time I only get the first 1024 characters returned. The problem seems to be that I am running into a PHP STRING limitation. From the reading that I have done on the subject, the limit should be 1024 characters PER LINE with the variable able to hold somewhere around 8MB worth of data. I can tell you that it does not matter how many \n I put into the HTML I still only get the first 1024 characters. Is there a way I can get the entire HTML file (about 12k characters) in memory so I can work with it and hand it off to the mail function? Thanks, whit3fir3 I am trying to insert a variable into this post string: curl_setopt ($ch, CURLOPT_POSTFIELDS, 'p_entity_name=The+Company+Name+LLC&p_name_type=A&p_search_type=BEGINS'); I want to replace company name with $name like: curl_setopt ($ch, CURLOPT_POSTFIELDS, 'p_entity_name='+ $name + 'p_name_type=A&p_search_type=BEGINS'); apparently I am doing this wrong. I want my string results from a form that searches DB content to appear within HTML table, tr, td tags. I get the results fine, but the HTML part isn't appearing. How should I be doing this? <?php $string = ''; $result = mysql_query($sql); /// This is the execution if (mysql_num_rows($result) > 0){ while($row = mysql_fetch_object($result)){ echo "<table>"; echo "<tr>"; $string .= "<td>".$row->last_name."</td> "; $string .= "<td>".$row->first_name."</td>"; $string .= "<td>".$row->employee_id."</td>"; $string .= "<td>".$row->title."</b>"; $string .= "<td>".$row->territory."</td>"; $string .= "<td>".$row->district."</td>"; $string .= "<td>".$row->Phase1A_Score."</td>"; $string .= "<td>".$row->Phase1B_Score."</td>"; $string .= "<td>".$row->Phase1_Average."</td>"; $string .= "<td>".$row->Phase1A_HS_Exam."</td>"; $string .= "<td>".$row->Phase1A_HS_Exam_RT."</td>"; $string .= "<td>".$row->Phase1B_HS_Exam."</td>"; $string .= "<td>".$row->Phase1B_HS_Exam_RT."</td>"; $string .= "<td>".$row->Class_Date."</td>"; $string .= "<td>".$row->Awards."</td>"; $string .= "<br/>\n"; echo "</tr>"; echo "</table>"; } }else{ $string = "No matches found!"; } echo $string; ?> Hey there. Thinking this should be an easy one but I can only seem to find info on the string replace function. What I'm trying to do is strip everything after the @ from an email variable. So for example $mail variable comes in as me@gmail.com How would I strip the variable to only contain me and remove the @gmail.com I'll keep searching for the answer myself but if anyone can throw me a bone it's be appreciated. Cheers Hello guys, basically i am doing a search function based on regular expressions. What i have done is to store the string i want to regex as a variable. Variable is named as $new_string -> preg_split("/\.\(.*\)\.\(.*\)/", $file); So inside the while loop, i would like to call another variable to store $new_string. However, I found out that the preg_split function stored inside $new_string doesn't work. If i use preg_split function directly inside the while loop it will work - > refer to //$parts = preg_split("/\.\(.*\)\.\(.*\)/", $file); I have troubleshooted it for like 1 hour plus.hope someone can help me thanks <?php //"$DOCUMENT_ROOT"."new/"; $current_dir = 'C:\xampp\htdocs\Audit_Reports'; //Put in second part, the directory - without a leading slash but with a trailing slash! $dir = opendir($current_dir); // Open the sucker $newArgument = $_POST[argument]; $newArgument1 = $_POST[argument1]; $string ='preg_split("/\.\(.*\)\.\(.*\)/", $file);'; $new_string = preg_replace("#\/\\\.\\\\\(\.\*\\\\\)#","/\.\\($newArgument\)",$string); $new_string = preg_replace("#\\\.\\\\\(\.\*\\\\\)#","\.\\($newArgument1\)", $new_string); echo ("<p><h1>List of Audit Reports:</h1></p><hr><br />"); while ($file = readdir($dir)) // while loop { //$parts = preg_split("/\.\(.*\)\.\(.*\)/", $file); $parts = $new_string; echo $parts; if (is_array($parts) && count($parts) > 1) { // does the dissected array have more than one part $extension = reset($parts); // set to we can see last file extension if ($extension == "Audit_Report" OR $extension == "audit_report") // is extension ext or EXT ? echo "<a href=\"$file\" target=\"_blank\"> $file </a><br />"; // If so, echo it out else do nothing cos it's not what we want } } echo "<hr><br />"; closedir($dir); // Close the directory after we are done ?> <form action="readdirectory.php" method='post'>Search Files:<p> Hostname: <input type="text" name="argument"<p> IP Address: <input type="text" name="argument1"<p> Date: <input type="text" name="argument2"<p> <p><input type="submit" name="submitFinal" value="Update"> <p> </form> </p> Hi Everyone, I have built a website utilizing a PHP abstract Webpage class to create the pages. When creating another class that inherits from Webpage class I rewrite abstract functions, etc. where needed. When instantiating an object of the extended classes I pass the constructor the $page_title, $css_file, $meta_data, $keywords, etc., etc.. I am able to pass html markup in a string variable to a class level "Setter" function to populate a "main area" of the website and all works perfectly. However, I have a contact form which I send the "Submit Message" button click to a PHP function that takes care of making sure the form fields are not empty, then sends email and returns a success message back to the calling page, if they are empty, the function returns what fields are empty(required). If the page includes empty and populated fields I want to put the populated fields into session variables so that I may populate the fields when the user is taken back to the page and display to the user the required fields that were empty(this functionality is already within the function). This brings me to my question(see code below for reference): Seeing that I am populating a variable with a string it seems I cannot use an if statement, echo or the like, my IDE gives me errors. How may I insert an if statement where needed to populate the empty form fields? Code: [Select] include('../php_functions/functions.php');//for the chechData() function $error_message = NULL; if(isset($_POST['submit'])) { $error_message = checkData($_POST, 'Renovation & Consulting'); } $main_content = '<form method="post" action=""> <fieldset id="contactform"> <legend>Renovations & Consultations</legend>'. [color=red]//placing a variable here works fine![/color] $error_message .'<div class="row_div"> <div class="label_div"> <label>First Name:</label> </div> <div class="input_div"> <input name="First Name" type="text" maxlength="50" size="50" value="'.[color=red]if(session variable not empty) echo it here;.'"[/color] /> </div> </div> <div class="row_div"> <input name="submit" type="submit" value="Send Message" /> </div> </fieldset> </form>'; Thanks for any and all responses. Chuck having issues with Code: [Select] echo curl_setopt($ch, CURLOPT_POSTFIELDS,"name='. $name .'&email='. $email .'&macs='.$mac_addresses.'&serial=".$serialnumber); the thing is $mac_addresses is a serialized array that should look like this Code: [Select] 4a:4:{i:0;s:14:"98340234820384";i:1;s:16:"0980342883408230";i:2;s:11:"72843729374";i:3;s:16:"4209384082304980";} but when I unserilize $mac_addressed and echo it I get Code: [Select] \'.a:4:{i:0;s:14:\"98340234820384\";i:1;s:16:\"0980342883408230\";i:2;s:11:\"72843729374\";i:3;s:16:\"4209384082304980\";}.\' can anyone see what my issue is? Hi, My issue here is that I cant get my query string variables to ONLY feed into if/else statement on my secondary page. I include my secondary page (fine.php) from my index page. My query string variables keep being fed back into my original if/ese statement on index.php. here is the if/else on index.php (these links work fine): <?php if($_SERVER['QUERY_STRING']=='/index.php' || $_SERVER['QUERY_STRING']=='') { include 'port.php'; } elseif (isset($_GET['pos'])){ include 'pos.php'; } elseif (isset($_GET['web'])){ include 'web.php'; } elseif (isset($_GET['fine'])){ include 'fine.php'; } else {include '404.php';} here is the if/else on my secondary page (fine.php). These links are supposed to alert the if/else in the next table cell. However, they instead alert the if/else in index.php. <td><br/> <a href="?backset"><img src="fine/thumbs/x-backset.jpg" border="0"></a><br/><br/> <a href="?backside"><img src="fine/thumbs/x-backside.jpg" border="0"></a><br/><br/> <a href="?bannerprint"><img src="fine/thumbs/x-bannerprint.jpg" border="0"></a><br/><br/> <a href="?chopu"><img src="fine/thumbs/x-chopu.jpg" border="0"></a><br/><br/> </td> <td><br/> <div id="DivPiece" align="left"> <?PHP if (isset($_GET['backset'])){ include 'fine/backset.php'; } elseif (isset($_GET['backside'])){ include 'fine/backside.php'; } elseif (isset($_GET['bannerprint'])){ include 'fine/bannerprint.php'; } elseif (isset($_GET['chopu'])){ include 'fine/chopu.php'; } ?> </div> </td> How can I get the links on the secondary page to only alert the if/else statement on that page, and BLOCK the if/else statement on index.php from seeing them? I still want to use the query string though. Thanks! [/quote] Could someone help me crack this issue. I am trying to insert a variable into an flash object echo string's src.

Maybe this is not the correct approach, i don't know. My goal is to attribute a string of a field of the form to a string variable in order to use this string variable in order to "auto fill" the field of the form previously completed. This is to do what is apparently called a sticky form... First the program attributes the string of a field of the form to a string variable : $EmitterFirstName = $_POST["EmitterFirstName"]; Then in the html form there is a field called "EmitterFirstName", and i want to use the string variable $EmitterFirstName in order to auto fill the field with the string previously typed by the user : <input type="text" name="EmitterFirstName" value="<?php $EmitterFirstName ?>"/> But it doesn't work as expected. Do you have any idea why or maybe an advice on how to code such a thing ? Thanks, For this example, $row2['author'] = "1" $user = 'user'.$row2['author']; if (!isset($$user)){ $result = $connector->query('SELECT * FROM users WHERE ID = '.$row2['author']); $$user = $connector->fetchArray($result); } echo '<a href="user.php?user='.($$user['ID']).'">'.$$user.'</a></p>'; The problem is it is a weird variable that also has an array, but when i use echo $$user['ID']; It errors out saying Notice: Quote Undefined variable: u So I am wondering how to word it to set the variable up properly, and how to call items in the array. Thanks in advance |
