PHP - Is Ajax Request
hey guys im tring to look for a good way of finding out if a ajax request is being performed on my page...now ive had a look about and found these two snippets.
Both seems to work fine...any suggestions on what one is best to use or even if there is a better way to do this would be helpful...thank you
if (isset($_SERVER['HTTP_X_REQUESTED_WITH']) &&
strtolower($_SERVER['HTTP_X_REQUESTED_WITH']) === "xmlhttprequest")
{
// is ajax
}
if (strpos($_SERVER['HTTP_ACCEPT'], 'application/json') !== false){
// is ajax
}
Similar TutorialsThis part of the question is based off of php so I'll put it here of course. The idea behind this is jquery/ajax is going to get passed an id (eventid) from a dropdown select box inside a form and it's going to run a query to find all the events in my database with that same id. After running the query it's going to list them out and find the highest number of another field (label) and its going to add one to its value and then what I would like for it to is send it back to the form in the jquery/ajax and and place that label inside of the existing input text field in the form. So I'm asking is if my code is presented and is doing what I"m attempting it to do on the php side and if so if I can take out the print tag of the input text field. $eventid = $_GET['eventid']; $result = mysqli_query("SELECT * FROM `events` WHERE `event_id` = '$eventid'"); $list = mysqli_num_rows($result); $label = $list + 1; print '<input type="text" name="label" class="text" readonly="readonly" value="' . $list . '" />'; This topic has been moved to Ajax Help. http://www.phpfreaks.com/forums/index.php?topic=347835.0 This topic has been moved to Ajax Help. http://www.phpfreaks.com/forums/index.php?topic=322771.0 Hi, I would like to send a value in a link and request it back in ajax and set it as a variable in php in the same page, can anyone help me here? thanks Hello forum,
So I've been developing an app mostly in PHP, but am rather afraid of JS. Hope to fix that.
I have an AJAX dropdown using JQuery to search locations. It works great. However, I want to make it similar to what is seen on this site:
http://placefinder.com/
As you can see, the dropdown, when clicked populates a box. Then the user submits the form and the data is used in the application.
I have no clue how to make the form populate with data from the DB (I'm using mySQL) when clicked. So far, I've only been able to make it clickable as a URL (not what I want, obvioiusly!)
Is there a way to do this on a really small, simple script for starters? I'm certain their is, but don't even know where to begin.
Any help appreciated

});
Doing something wrong, but don't see it. How should one retrieve a POST parameter? My $request->toArray()['html'] works, but I am sure it is not the "right way".
<?php
namespace App\DataPersister;
use ApiPlatform\Core\DataPersister\DataPersisterInterface;
use Symfony\Component\HttpFoundation\RequestStack;
class ArchivePersister implements DataPersisterInterface
{
public function __construct(RequestStack $requestStack)
{
$request = $requestStack->getCurrentRequest();
syslog(LOG_ERR, '$request->getMethod(): '.$request->getMethod());
syslog(LOG_ERR, '$request->getContent(): '.$request->getContent());
syslog(LOG_ERR, '$request->request->get(html): '.$request->request->get('html'));
syslog(LOG_ERR, '$request->query->get(html): '.$request->query->get('html'));
syslog(LOG_ERR, '$request->get(html): '.$request->get('html'));
syslog(LOG_ERR, '$request->toArray(): '.json_encode($request->toArray()));
syslog(LOG_ERR, '$request->toArray()[html]: '.$request->toArray()['html']);
}
}
output
$request->getMethod(): POST
$request->getContent(): {"project":"/projects/1","description":"","html":"<p>{{ project_name }}</p>"}
$request->request->get(html):
$request->query->get(html):
$request->get(html):
$request->toArray(): {"project":"\/projects\/1","description":"","html":"<p>{{ project_name }}<\/p>"}
$request->toArray()[html]: <p>{{ project_name }}</p>
Right now I redirect to index page after I delete a record. However I am looking to make it so that I can delete a record without redirecting the page. I know this can be accomplised using Ajax. I have spent countless hours before trying to make it work, but it did not work.
So here is a basic setup I created. Can you please update it with ajax code so that I can see how it's done properly?
<!DOCTYPE HTML> <html lang="en"> <head> <meta charset="UTF-8"> <title>Home Page</title> </head> <body> <div class="record" > <a href="record.php?id=<?php echo $record_id ?>"><?php echo $record_name; ?></a> <div class="delete-record"> <a href="delete.php">Delete Record</a> </div> </div> </body> </html> Edited by man5, 18 August 2014 - 08:55 PM. Now I'm having this strange issue with my website I'm currently working on a tester system and I've encountered a problem that I'm unable to find the issue, tho I'm thinking my ajax php part of the script to be the thing causing it even tho it seems strange that it would cause it. The first part which is connected to where the problem occurs is the echo"<form>"; and from there, It should take you to index.php?page=tester&select=answer, now that is where it in the browser goes there tho it still shows the page stuff from the last page which is index.php?page=tester&select=applications, so it's like showing both &select=answer and &select=applications on the same page. <?php $q=$_GET["q"]; include'../config/connection.php'; $result = mysql_query("SELECT * FROM applications WHERE id = '$q'"); echo "<center><table border='1'> <tr> <th>Account Name</th> <th>Character Name</th> <th>Gender</th> <th>Skin Color</th> </tr>"; $row = mysql_fetch_array($result); echo "<tr>"; echo "<td>" . $row['name'] . "</td>"; echo "<td>" . $row['charactername'] . "</td>"; echo "<td>" . $row['gender'] . "</td>"; echo "<td>" . $row['race'] . "</td>"; echo "</tr></table></center>"; echo"<br/>"; echo"<table><tr> <th>Description</th> <th>Metagaming</th> <th>Powergaming</th></tr>"; echo"<tr>"; echo "<td><textarea readonly='readonly' style='width:22em; height:20em;'>".$row['description']."</textarea></td>"; echo "<td><textarea readonly='readonly' style='width:22em; height:20em;'>".$row['mg']."</textarea></td>"; echo "<td><textarea readonly='readonly' style='width:22em; height:20em;'>".$row['pg']."</textarea></td>"; echo"</tr></table><table><br/><center><h1>Answer</h1><br/><form action='index.php?page=tester&select=answer' method='post'>"; echo"<textarea name='why' style='height:10em; width:60em;'></textarea><br/>"; echo"<input type='submit' name='answer' value='Accept' /><a/>"; echo"<input type='submit' name='answer' value='Decline' /></center>"; echo"<input type='hidden' name='id' value='$q'/>"; echo"</form></table>"; ?> Now on &select=answer it included a page which the script of that include consist of the stuff below, it outputs that the query was successfully, and all that. <? if(!empty($_POST['why'])) { $why = mysql_real_escape_string($_POST['why']); $answer = trim($_POST['answer']); $id = $_POST['id']; if($answer == "Accept") { $query1 = mysql_query("UPDATE characters SET accepted = '1' WHERE id = '".$id."'"); echo"Successfully accepted"; $answer = 1; } elseif($answer == "Decline") { echo"Successfully declined"; $answer = 0; } $query = mysql_query("UPDATE applications SET answer = '$why' AND tester = '".$_COOKIE['Username']."' AND accepted = '$answer' AND answered = '1' WHERE cid = '".$id."'") or die('Could not connect: ' . mysql_error()); if($query) { echo"<br/>Query went through without problems"; header("Refresh: 5;url=index.php?page=tester"); } } ?> This is the ajax part javascript of it which gets the information for index.php?page=tester&select=applications Code: [Select] <script type="text/javascript"> function showApplication(str) { if (str==""||str==0) { document.getElementById("txtHint").innerHTML=""; return; } if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari xmlhttp=new XMLHttpRequest(); } xmlhttp.onreadystatechange=function() { if (xmlhttp.readyState==4 && xmlhttp.status==200) { document.getElementById("txtHint").innerHTML=xmlhttp.responseText; } } xmlhttp.open("GET","tester/applications.php?q="+str,true); xmlhttp.send(); } </script>If you need any more information feel free to ask for it. Thanks in advance. Hello, I've been trying this for hours now, looking at different examples and trying to change them to work for me, but with no luck... This is what I am trying to do: I have a simple form with: - 1 input field, where I can enter a number - 1 Submit Button When I enter a number into the field and click submit, I want that number to be send to the php file that is in the ajax call, then the script will take that number and run a bunch of queries and then return a new number. I want that new number to be used to call the php script via ajax again, until no number is returned, or something else is returned like the word "done" or something like that, at which point is simply makes an alert or populated a div with a message... The point is, that depending on the number entered it could take up to an hour to complete ALL the queries, so I want the script that is called to only run a fixed amount of queries at a time and then return the number it is currently at (+1), so that it can continue with the next number when it is called again. I would like to use jquery, but could also be any other way, as long as I get this to work. I already have the php script completed that needs to be called by the ajax, it returns a single number when being called. Thank you, vb As the title say, I can not for the life of me get the "$bank" content to display, no matter HOW much I try... Does anyone see any errors.

But anyways am having an issue. I am trying to make a standard template page. On a prior site I had it set up this way with the code I will post below and it worked for me but I have tried to implement it on this site and am not having any luck. Few things on the code below. It was designed for another site. So what I need is as follows. The home page should bring up the default index.txt file. That has the home page info on it. Second the code below has a table in the coding as I required a table on my site so that is in the code but for this site don't need the table. There is also one image in the code. That too is no longer required. I will just leave these in place that way you can see the code I am working with so you can hopefully correct it to work for me as I am going nuts trying to get this to work. Also somewhere in the coding it seems maybe there is an open link tag as I did get this to work a little bit but for some reason when it was the TXT file information was also being made to be a link even though the txt file for time being only contains basic text no coding what so ever. Now what I need is as follows. Default home page TXT file loaded when home page loads. But the link below is what I was using for my site and when this was clicked it would load the TXT file for that page so the example link below would open up a members page that was associated with my message board I was using. Code: [Select] <a href="members.php?categories_file=Members">Forum Members Websites</a> that link would bring up file members.txt which was stored in the text folder Below is the code that in both cases was and is placed in the main window of the table I am using for layout. Last time this all worked perfectly but this time not sure why it refuses to load the page like it use to. Can anyways sort this code so it works fine for me. Thanks!! Dave Code: [Select] <?php if ($_GET['categories_file']) $fp = fopen("text/$categories_file.txt", "r") or die("Could not open $categories_file."); while (!feof($fp)) { $line = fgets($fp, 512); $categories[] = $line; } asort($categories) or die("Could not sort array."); $table_column_counter = 0; echo "<table border='0' cellpadding='0' cellspacing='0' width='90%'>"; foreach ($categories as $item) { if ($table_column_counter == 0) { echo "<tr>\r\n"; } $link = explode(",", $item); echo "<td><img src='images/green.gif' width='13' height='13'><a href='$link[1]' target='_blank'>".$link[0]."</a></td>"; if ($table_column_counter == 2) { echo "</tr>\r\n"; } $table_column_counter = $table_column_counter + 1; if ( $table_column_counter >= 2 ) { $table_column_counter = 0; } } ?> hi, can anyone please check my code it has an error Quote invalid content type for request: application/x-www-form-urlencoded Code: [Select] <?php $request = "<?xml version='1.0'?><request><br> <authentication><br> <username>username</username><br> <password>password</password><br> </authentication><br> <operation>getResellerProducts</operation><br> <params><br> <int>22</int><br> </params><br> </request></myXML> "; $url = "https://testapi.ssl.trustwave.com/3.0/"; // fake - obviosly! $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_POSTFIELDS, $request); // what to post curl_setopt($ch, CURLOPT_BINARYTRANSFER, 1); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0); $result = curl_exec($ch); curl_close($ch); print $result; ?> thanks! hello guys , can you guys see any errors in this code`? i cant seem to find it <?php $units_stats_1 = array(40, 35, 50); $units_stats_2 = array($units_stats_1[0] * 50%, $units_stats_1[1] * 100%, $units_stats_1[2] * 100%); echo $units_stats_2; ?> i allso tryed to do : echo $units_stats_2[0]; thanks I'm struggle to build an appropriately formatted URL request for a particular API (not really important which, but it's for Toodledo). The API documentation says: Quote Tasks are edited by POSTing a URL encoded JSON encoded array to the API. Each element in the array will be a task object. You only need to set the fields that you want to set. For efficiency, you should try to send only the fields that have changed. At this time it is not possible to post XML data to Toodledo. http://api.toodledo.com/2/tasks/edit.php?key=YourKey; tasks=[{"id"%3A"1234"%2C"title"%3A"My Task"}%2C{"id"%3A"1235"%2C"title"%3A"Another Task"%2C"star"%3A"1"}]; fields=folder,star I've tried about 100 different combinations of code like the following: $arr = array ('id'=>$id,'completed'=>1,'reschedule'=>1); $tasks = json_encode(array($arr)); $params = array('key'=> $this->key); $params['tasks'] = $tasks ; $params['fields'] = 'id,completed,reschedule' ; $url="http://api.toodledo.com/2/tasks/edit.php?".http_build_query($params) ; $response = file_get_contents($url); None seems to get me to a URL formatted like they ask. Can someone help me out? I'm tired of banging my head against the table. [Note... the fields I'm passing in single element of the $tasks array are different than in the example... but it's the format, not the content, that I can't get right] Thanks in advance! I am very confused at an example in a book I am reading called Beggining PHP regarding XML-RPC requests. I will write the code below: function send($remoteServer, $remotePort, $fullXMLRPCRequest) { $headers = ''; $data = ''; $socket = fsockopen($remoteServer, $remotePort); fwrite($socket, $fullXMLRPCRequest); while ($str = trim(fgets($socket))) { // why doesn't this exhaust the returned call?? $headers .= $str . "\n"; } while (!feof($socket)) { $data .= fgets($socket); } fclose($socket); return $data; } The question I have is notice how there are two while statements and they both access the same resource ($socket). So how can there be two while statements?? Wouldn't the first while statement exhaust the resource and there would be nothing on the second while statement? I hope this makes sense. It's sort of like saying while(x < 10) { //execute... ++x; } then another while statement while(x < 10) { //execute... ++x; } Well then wouldn't the second while statement not execute? I hope I made sense. Thanks for all the help in advance. Obviously knowing XML-RPC would help in answering this question, hopefully most of you are familiar with it. Hello, I am using the send mail form, everything is sent to my mail except the country field, it is sending blank. Code: [Select] $name = $_REQUEST['name'] ; $phone = $_REQUEST['phone'] ; $email = $_REQUEST['email'] ; $country = $_REQUEST['country'] ; $message = $_REQUEST['message'] ; $headers = "From: $email"; $sent = mail( $to, $subject, $name."\n".$phone."\n".$email."\n".$country."\n".$message, $headers); How could it be fixed please? thanks Hi, I don't know very much about php. I don't know any at all, actually. I play a game called Roblox where you get to use the programming languange, "Lua" to script your own games. What I am requesting has been done before on this game, but I only know Lua. I was also told PHP cURL is needed. Anyways, let me get to the point. I am essentially trying to create a system on my webserver (You can send HTTP Requests to external sites in this game via script) that will essentially log into an account on Roblox, to perform a task. My current idea would be to have the Lua script send a request to my webserver with an generated code that would access the username and password of my roblox account (Which would be on the webserver). It would then perform a task. Is this a good way to go about this? If not, I am open to suggestions. If you can find the time to actually help me set this up on my webserver, I would greatly appreciate it! I'm also sorry if this is the wrong place for this post, I'm new here. I am new to all this, so please help I want to create a request form, basically when I click onto a hyperlink on my web page I want it to call windows explorer with the following ftp;//test.co.uk (example), which will bring up the page and I can log in. Any help would be a much appreciated I am using the code below to query a url. It should return the response in xml bu all i get is a string back. $url = 'https://services.example.org/webservices/xget.php?ProductIDValue='.$_GET['pid'].'&ProductIDType=01&ONIXRecordFormat=03&ClientID='.$GLOBALS['user'].'&ClientPassword='.$GLOBALS['pass']; $r= new HttpRequest($url, HttpRequest::METH_GET); $r->send () ; echo $r->getResponseBody() ; 1. How can i get the response as xml 2. How can i display the response on my web page Thanks a lot for your help |
