PHP - How To Get Rid Of Backslashes Passed Through $_get
Good day freaks. I am pulling my hair out trying to figure this out. I am trying to pass patterns for preg_replace through $_GET and then apply them. The object is to highlight certain words in a chunk of text.
Say I want to highlight bounded cases of 'foo' in the text. So here's what I'm doing: Code: [Select] $string = urldecode($_GET['highlight1']); // $string contains \\bfoo\\b $search = preg_replace('/\\\\b/','b',$string); // $search contains \bfoo\b as I want it to $replace = preg_replace('/\\\\b/','',$string); // $replace contains \foo\ >:-( $pattern = '/'.$search.'/i'; $text = preg_replace($pattern,'<span style="background-color:yellow;">'.$replace.'</span>',$text); The problem is that no matter what I try for the pattern for $replace, it winds up with backslashes around foo. How do I get rid of these? (I should say that I discovered the pattern/replace for the $search string by experimentation and I don't understand why the pattern doesn't pick off all the backslashes in that case--but at least it does what I want). TIA Steve Similar TutorialsFolks, I am trying to grab the value selected in a Dropdown, with $_GET['q']. Then i am echoing the grabbed value. Funny thing is, when i select value from HTML dropdown (onchange="location=this.value"), and when a new value is selcted, it appaears in url like this: Quote http://www.abc.com/?search=selected-value.html But when i try to grab and echo the value of 'q' it gets passed only when i refresh the page and not when i change my selecting in dropdown. Am not sure whats happening, can someone help me on this? Cheers NT Hi there! i get_file_contents from a .txt file. For example if I typed "don't" Don\'t would be displayed. Why is this? Thanks
I recently fixed a bug in my own website involving preg_replace, the thing is, each time I was editing an article in the front-end, preg_replace would be called on the HTML to replace certain HTML elements.
$html = '<div>REPLACEMENT_ID</div>';
$replacement_id = 'REPLACEMENT_ID';
$replacement = addslashes('<pre>\\\\</pre>');
// $html = preg_replace("|{$replacement_id}|", $replacement, $html);
// $html = str_replace($replacement_id, $replacement, $html);
$pos = strpos($html, $replacement_id);
if ($pos !== false) {
$html = substr_replace($html, $replacement, $pos, strlen($replacement_id));
}
print_r($html);
A few months ago, and a good amount of time before that, I had people telling me to use isset() instead of performing to see if the variable is empty, such as: !$_GET[''] I know the differences in the function and what they do, but when could isset() be used in a situation where it's better/more efficient then: !$_GET[''] I do use isset(), though. Hello! I want to be able to make a code that tells me how many saturdays have passed till today. I've tried a couple of things but nothing. Any help?! Thanks! Hi all, How can I check in PHP if this date has already passed in the following format: 2012-12-12 Hi I use Dreamweaver to do a lot of my work on a php/mysql database. I have two tables - applications and contacts and they are linked by the id appid. When I view a page with all of the application and contact details the url contains the appid as a number at the end (eg .../Summary.php?appid=639) When I want to edit one of the contacts I go to the edit page but this is identified by a contact id so that url looks like: ../EditContact.php?contactid=32 When I update the contact's details I would like to return to the summary page but can't as the url gets muddled between the two different ids so I end up at a page with no info on it. How can I get round this? I'm sorry my explanation isn't very clear but any help is much appreciated. Hi I am trying to get all variables passed in a url string and wondered how would i do it? I dont know what they are yet and i need to set key as value. Any help? I am trying to pass a php variable to javascript but it's not working. This is the "sketch" of my code. <?php $url="asset/go/"; ?>
<!DOCTYPE html>
<html>
<head>
<title>Page Title</title>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script>

<body>
<script>
var user="mayor";
var url ='<?php echo json_encode($url); ?>';
if(user=="mayor"){
alert(url);
}
</script>
</body>
</html>
As it is now, it comes with the output below: <?php echo json_encode($url); ?> If I remove the quotation around the php in d jQuery, it throws an error in syntax. Also both codes are located in the same file named test.php Thanks in advance. Edited April 18 by Abel1416In my main script I set $errorArray with values when required survey questions go unanswered. The ne code that checks for missing required values is working perfectly, and right before I pass $errorArray to a function which rebuilds the survey questions - this time with the error messages - I do a var_dump($errorArray) and that array has errors in it as expected. But while my function that re-builds the survey questions gets called and does indeed re-build the survey questions, the $errorArray isn't getting pased for some strange reason? (I'm not sure if i have ever passed an array to a function before.) In my function I have...
function generateSurveyItem($dbc, $questionNo, $questionID, $surveyResponseArray=NULL, $errorArray=NULL){
}
When I var_dump($errorArray) at the top of the function, and submit a blank form, I end up with a blank page and a file path to my PHP script ending with... /public_html/utilities/function.php:3010:null
Questions: 1.) What is happening?
2.) I thought =NULL in the parameter list just meant that the argument is "optional"?
3.) I am able to successfully pass $surveyResponseArray to this function, so what is up with $errorArray?
P.S. When I run things, and submit an empty form - thus no "required" fields get completed - the survey gets re-displays, and any values chosen are "sticky", but my error messages should also be displayed to let the user know what is mising, and that is the part that isn't working? This has to be something silly stupid to fix... Edited February 16 by SaranacLake
Hi All, I've been trying to access xml data from an API feed, but it needs a Variable to be passed to an include file without a form. the include is at the header of the page. in the code below, i'm trying to retrieve the variable $project_add from the $xml_2 feed. $proj_add_ID comes from another feed and is being passed ok.
foreach ($projects_1 as $proj_1) {
$job_no =$proj_1['job_no'];
$job_name =$proj_1['job_name'];
$job_status =$proj_1['job_status'];
$job_staff =$proj_1['job_staff'];
$job_due =$proj_1['job_due'];
$clr_1 = $colors_1[$job_status];
if ($err_2) {
echo "cURL Error #:" . $err_2;
} else {
$_POST['job_id']= $job_no;
$xml_2=simplexml_load_string($response_2) or die("Error: Cannot create object");
$proj_add = $xml_2->xpath("CustomFields/CustomField[ID ='$proj_add_ID']");
foreach($proj_add as $item_2) {
$project_add = "$item_2->Text";
}
echo "<div class='row no-gutters'>";
echo "<div class='col-sm bg-white border rounded'><a href='managejob.php?job_id=$job_no' class='text-left ml-1'><strong>$job_no</strong></a></div>";
echo "<div class='col-sm-2 bg-white border rounded'><p class='text-left ml-1'>$job_name</p></div>";
echo "<div class='col-sm-2 bg-white border rounded'><p class='text-left ml-1'></p>$project_add</div>";
echo "<div class='col-sm-2 bg-white border rounded'>" . state_dropdown_1($job_no, $job_status, $clr_1) . "</div>";
echo "<div class='col-sm-2 bg-white border rounded'><p class='text-left ml-1'>$job_staff</p></div>";
echo "<div class='col-sm-2 bg-white border rounded'><form action='CALL_API_PUTTaskDate.php' method='POST'>"
. "<input type='hidden' name='task_ID' value ='". $jdata['task_ID'] ."'>"
. "<input type='hidden' name='est_min' value ='". $jdata['est_min'] ."'>"
. "<input class ='form-control bg-white text-dark font-weight-bold' type='date' name='start_date' value='" . date('Y-m-d', strtotime( $jdata['display_date_1'] )) . "' onchange='this.form.submit()'>"
. "</form></div>";
echo "<div class='col-sm bg-white border rounded'><p class='text-left ml-1 mt-1'><strong>" . date('d/m/Y', strtotime( $jdata['display_date'])) . "</strong></p></div></div>";
}
The include file is like this
/ collect Custom Felds
if ($_SERVER["REQUEST_METHOD"] == "POST") {
// collect value of status input field
$job_no = $_REQUEST['job_id'];
}
if (isset($_POST['job_id'])) {
$job_no = $_POST['job_id'];
}
if (isset($_GET['job_id'])) {
$job_no = $_GET['job_id'];
}
$curl_2 = curl_init();
curl_setopt_array($curl_2, array(
CURLOPT_URL => "https://api.xxx.com/job.api/get/$job_no/customfield?apiKey=xxx&accountKey=xxx",
CURLOPT_RETURNTRANSFER => true,
CURLOPT_ENCODING => "",
CURLOPT_MAXREDIRS => 10,
CURLOPT_TIMEOUT => 30,
CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
CURLOPT_CUSTOMREQUEST => "GET",
CURLOPT_HTTPHEADER => array(
"Accept: */*",
"Accept-Encoding: gzip, deflate",
"Cache-Control: no-cache",
"Connection: keep-alive",
"Host: api.xxx.com",
"Postman-Token: xxx",
"User-Agent: PostmanRuntime/7.17.1",
"cache-control: no-cache"
),
));
$response_2 = curl_exec($curl_2);
$err_2 = curl_error($curl_2);
curl_close($curl_2);
The problem is the variable $job_no isn't getting passed to CURLOPT_URL so it's not retrieving the data required. i need to be able to retrieve this data without submitting a form as it's in a foreach loop and the Id is specific to each iteration. is there a way to do this? I have been able to achieve this by putting the include within the div tags that it will be displayed but it just slows down everything too much and hangs. Any help will be much appreciated. Kind regards, Michael Bennington. Hi, I want to update a row when 30sec are passed on a page. If not nothing happens(not updating row). Example: You go to example.php>> 30sec pass, update row>> 30sec not over, no update. it does not necessarily have to be second it can be minutes or hours. Who can help me? Hope its clear enough, Thanks. i've been programming in PHP for years, and have done a substantial amount of work on applications of this nature. this problem has me stumped, not because i can't fix it (i did), but because i have no idea what the problem is. there are hundreds of lines of code involved here, so i'll break it down into a post-friendly format. take this for example, and forgive any typos. it's late, and i've been beating my head against this for over two hours... =\ this is from my form: Code: [Select] /* ... numerous form fields being passed as $_REQUEST arrays */ <input type="hidden" name="option_id[]" value="<?php print $query_result->option_id; ?>" /> /* a couple hundred more lines */ here's the DB update handler: Code: [Select] if (!empty($_REQUEST['option_name'])) { foreach ($_REQUEST['option_name'] as $k => $v) { if ($v != '') { $option_id = $_REQUEST['option_id'][$k]; $option_name = $_REQUEST['option_name'][$k]; $option_price = $_REQUEST['option_price'][$k]; $option_desc = htmlentities($_REQUEST['option_desc'][$k], ENT_QUOTES); if (!$option_id = '') { $sql_options = "UPDATE table SET" . " option_name = '" . $option_name . "', option_price = '" . $option_price . "', option_desc = '" . $option_desc . "' WHERE option_id = '" . $option_id "'"; if (!$query_function($sql_options)) { $error = true; } } else { $sql_options = "INSERT INTO table (option_name, option_price, option_desc)" . " VALUES ('" . $option_name . "', '" . $option_price . "', '" . $option_desc . "')"; if (!$query_function($sql_options)) { $error = true; } } } } } the above code doesn't post to the database because the $option_id variable returns a null value. however, if i replace the $option_id variable where i build the query string with $_REQUEST['option_id'], it works just fine. Code: [Select] /* in relevant part */ $sql_options = "UPDATE table SET" . " option_name = '" . $option_name . "', option_price = '" . $option_price . "', option_desc = '" . $option_desc . "' WHERE option_id = '" . $_REQUEST['option_id'] . "'"; needless to say i was infuriated by having spent a couple of hours to come to this conclusion. i only used the variables in the first place because i need to expand the function that this lives inside and i don't want to have to type $_REQUESTs over and over. the only thing i can think is that it might be a type issue. the data is coming out of the mysql table from an INT field and being placed into the value for the hidden field straight from the row collection. would forcing a variant data type by not strongly typing my variable have caused this problem? i haven't tested the theory because i'm still too ticked off to open my code editor. i'm bouncing this off the community and posting my experience in the hope that it might help someone who comes after. Hey all, I'm very new to php and am having an issue writing to my database with a passed value and info taking from a form and am lost as to what to do. The $comm_id is the value I am getting from another php page that I am passing in the link from the other page. I need to insert that value, the session variable, and the $cmt value, which is taken from the user input from the form. As it stands now, when I run this, the $comm_id and $u_id insert and the $cmt is blank, BUT $cmt is echoing on the screen with the proper value. Any tips or direction would be great as i've been trying to sort this out for days now and i'm stumped. <?php $host='localhost'; $user='username'; $password='password'; $dbname='db_a'; session_start(); $id_link=mysql_connect($host,$user,$password); mysql_select_db($dbname, $id_link); $comm_id = $_GET['commId']; $u_id = $_SESSION['userId']; echo $comm_id; echo $u_id; $cmt = $_POST["comm"]; mysql_query("insert into Comments values($u_id, $comm_id,'$cmt');"); echo $cmt; ?> <FORM ACTION="test.php" METHOD="POST"> <input type="text" name="comm"> <input type="SUBMIT"> </FORM>
<?php
global $places;
$comm = $GLOBALS["location"];
$comm=trim($comm);
while(list($one,$two) = each($places))
{
echo "<option value=\"$two\"";
if ( $two == $comm)echo "selected ";
echo ">$two</option>\n" ;
}
?>
Variable passed to each() is not an array or objectHi, my code works fine but it is giving the error message Please can anyone help? Thanks I think I've gotten as far as I can with my troubleshooting so hopefully someone can help me here. I have a constructor for a controller class that receives the $_SESSION array from index.php by reference. An instance variable is then created when references this references so that any changes made to this instance variable update the real $_SESSION variable. This was working until it mysteriously stopped after not touching it for a few hours. The local $this->session variable is working because it completes some tasks using it. I've also hardcoded values into the session from the index.php file and when they are hard coded the session works as you would expect so it seems to just not be connecting this local variable to the $_SESSION array anymore for some reason. index.php snippet: Code: [Select] session_start(); $action = 'login'; $controller = new UserController($_POST,$_SESSION); call_user_func(array($controller,$action)); constructor and login action from UserController (constructor is actually from a base controller but that shouldn't matter). Also the activeSession() function that checks if a session is valid and kicks the user if its not (which is what happens when anything is tried after logging in): Code: [Select] function __construct($post,&$session){ $this->post = $post; $this->session = &$session; $this->view = 'views/login.php'; $this->title = ''; $this->error = ''; } function login(){ try{ $user = $this->validateString($this->post['username'],'Username'); $pass = $this->validateString($this->post['password'],'Password'); $dao = new UserData(); $this->session['userid'] = $dao->login($user, $pass); $this->session['username']=$user; $dao = new PostData(); $this->posts = $dao->getFeedPosts($this->session['userid']); $this->view = 'views/posts.php'; $this->title = 'Post Feed'; } catch(Exception $e){ $this->handleException($e); } } function activeSession(){ if(!empty($this->session['userid'])) return true; else return false; } Any help would be amazing. I really don't know how this stopped working. Thanks in advance. hey guys so I have this code: $result = mysql_query("SELECT * FROM pec_mssgs ORDER BY (y / m) DESC, d ASC"); while($row = mysql_fetch_array($result)) { echo "•<a style='text-decoration: underline; font-weight: bold;' href='../index?id=".$row['id']."'>". $row['m']."/".$row['d']."/".$row['y'] . " - ".$row['title']."</a>"; echo "<br /><br />"; } in my database instead of doing date I have 3 rows d, m, y, which correlate to day, month, year. now currently its echo out a list and sorting by year then month then day this way the events which are happening soonest will be at top. the problem is it shows events that has already passed. what do I do? It will be way to much work to to back and recode the application to just use date. is there a way I can create a var. using my d/m/y then compare that var. to the current date or something? thanks for the help. hi there, this is a general question where i am confused over long time.. what is the used of passing big encrypted strings in the url? most of the time i see in big sites like google / yahoo. and what are the uses of this in real time .. or they are just made big to confuse hackers?. any explanation would be highly helpful!. example as below http://yahoo.com/_ylt=AsXHbMLeE2zV.1Tq082xTdiuitIF/SIG=11licq9d2/EXP=1283427670/**http%3A//mail.yahoo.com/%3F.intl=en http://click.email.microsoftemail.com?qs=06f2de8ca524e4650483090ed07957e8da3dbc0db662e7f97fa1b5d384b45a28800d5407dd3daa63 I have a forum script I made that has thread bumping for the thread creator only. I am trying to limit the amout of time the creator can bump to be every 10 minutes. Here's my code. list($title, $creator, $locked, $hidden, $moved, $lastbump) = mysql_fetch_row(mysql_query('SELECT title, creator, locked, hidden, moved, lastbump FROM forum_threads WHERE id="'.$_GET['threadid'].'"')); if(($locked == 1 || $hidden == 1 || $moved == 1) && !$_SESSION['rights'] == 2){ header("location: thread.ws?id=".$_GET['threadid']."&page=".$_GET['page'].""); } else { if($creator == $_SESSION['username']){ mysql_query("UPDATE forum_threads SET lastbump = NOW() WHERE id='".$_GET['threadid']."'"); } else { header("location: thread.ws?id=".$_GET['threadid']."&page=".$_GET['page'].""); } } Hi, I am a beginner with php and I am having a hard time understanding a section in my code. The part I dont get is why we have to minus 1 from the number being passed into the array. For example, $FaceNamePlural[$die1-1] I tried looking at it over and over but I'm still very confused. Can anyone help me on this...Thanks.
