PHP - Moved: Ajax Call Issue?
This topic has been moved to Ajax Help.
http://www.phpfreaks.com/forums/index.php?topic=334644.0 Similar TutorialsHello, 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.

Please help me out. Hello guys is it possible to create a single php file to contain all the functions to be called via AJAX and get AJAX to call the specific function required rather than having to create individual pages for each AJAX request you need to make? Many Thanks Hi
I have an AJAX call that populates a select menu based on the selection from a previous menu. All works on on desktop browser, Safari, Firefox IE etc, however when using iOS the second select menu isn't populating.
the AJAX request is as follows
<script>
function getXMLHTTP() { //fuction to return the xml http object
var xmlhttp=false;
try{
xmlhttp=new XMLHttpRequest();
}
catch(e) {
try{
xmlhttp= new ActiveXObject("Microsoft.XMLHTTP");
}
catch(e){
try{
xmlhttp = new ActiveXObject("Msxml2.XMLHTTP");
}
catch(e1){
xmlhttp=false;
}
}
}
return xmlhttp;
}
function getTeam(strURL) {
var req = getXMLHTTP();
if (req) {
req.onreadystatechange = function() {
if (req.readyState == 4) {
// only if "OK"
if (req.status == 200) {
document.getElementById('away-team').innerHTML=req.responseText;
} else {
alert("There was a problem while using XMLHTTP:\n" + req.statusText);
}
}
}
req.open("GET", strURL, true);
req.send(null);
}
}
function getGP(strURL) {
var req = getXMLHTTP();
if (req) {
req.onreadystatechange = function() {
if (req.readyState == 4) {
// only if "OK"
if (req.status == 200) {
document.getElementById('gp').innerHTML=req.responseText;
} else {
alert("There was a problem while using XMLHTTP:\n" + req.statusText);
}
}
}
req.open("GET", strURL, true);
req.send(null);
}
}
</script>
and the trigger for it...
<select name="year" class="txtfield" onChange="getGP('find_gp_ajax.php?season='+this.value)">
Any ideas why the call won't work on iOS?
Can anyone figure out why this works in IE and Firefox but not Safari? Any help would be great.

I then prepend it into a div area called code_content. I use some php str_replace to add some links also. When the content loads into the div, the user can then add further content to it via Ajax calls, appending articles and that. What I'm trying to figure out is how can I then retrieve all the newly edited contents of this code_content div soni can send it to my Ajax function to write to te db? Hi, This is my first post in this forum and am a PHP beginner. I have written a script in php and need to use echo to see the values of variables etc. However I dont get the output on the screen while using echo . I am using Xampp server with Apache. The startup.html file code is
<!DOCTYPE HTML>
</head>
and the test.php code is <?php
$lat = $_REQUEST['latitude'];
echo 'latitude- '.$lat . ', longitude- ' . $lon; Please help regards
Sanjish I have a page that functions like this:
The user begins by loading ajaxtest.php, then using a drop-down menu, selects a user, after which a DIV on ajaxtest.php is populated with the user's selction to getuser.php?q=John%Doe
Here's a visual representation of what is currently happening, along with the part I don't understand.
getuser.php consists largely of a a large HTML table which interacts through PHP with my SQL database. Several of the fields in this table are editable, and after the user changes one of these fields, he can press an "update" button, which calls an AJAX script in update.js and runs update.php, which contains all my SQL queries to update the database, without the user being redirected to this update.php page. All of this is processing perfectly - the user makes some sort of edit, hits "update", and the database gets updated without any redirection or refresh.
Here's what I can't figure out though. Once the user makes a change, and hits "update," the database updates, but the end user doesn't see those changes that he made. I can't just do a simple page refresh, because the action is taking place on getuser.php, but getuser.php is loaded inside of a #DIV on ajaxtest.php. If I use something like window.location.reload(), this just refreshes ajaxtest.php and puts the user back to the starting point of having to select a user. This is not what I want. I don't want to refresh ajaxtest.php, I want to "refresh" ajaxtest.php with getuser.php?q=John%Doe insidethe DIV on ajaxtest.php.
It seems like this is very common - several forums have this capability, where a user has a page loaded, adds a comment, and sees that comment immediately without a full page refresh. I just don't know how to do it, and I've tried at lengths to search the web for an answer with no luck.
Can someone walk me through how to do this?
Where is my "Progr" return value?
This is not my first day using php but I don't code in the language that often. I don't understand why my dynamic variable is not returned in AJAX GET? Essentially, I need to give the client a simple UI so that they can copy files to a printer and I wanted to provide a little unfiltered feedback so they knew whether operation was a success. My feedback was just going to be output of exec() function though cleaned up slightly (perhaps replace line breaks with html break tags). PHP version is 5.2.17.17 and cannot be upgraded. Web Server Apache.
PHP dumbed down code:
exec("LoadZPL_PURL.bat", $output); Hello all I have a php and jquery/ajax call I am using to create a file/send an email. I get all the contents from my textboxes but I want a message to display on the screen afterwards being success or fail. In my .ajax call My call is exiting right before the ‘success:’ part. Why is my call not succeeding? Any tips/help will be appreciated Thank you

Hello All, I have a PHP web application which will refresh itself(ajax calls connecting to the server and get the latest data) periodically. These also update the Database-based session handler class. i.e. There is NO UPDATE to the session data but the timestamp is constantly updated. Our problem is that garbage collection does not kick in as it looks at the difference between timestamp and session_gc.maxlifetime. So, if and the user is not interacting with the application. Now my question is how can I force the timeout even though refreshing happens but the user is not interacting with the application and there are "phantom" session updates made by these ajax calls. Please let me know. Thanks. I have a dropdown that is on two levels. The first drop down is populated with the county list from my database. It returns the county in a drop down of what data is in the database. Then when you select the county you want the second list is populated with the city. The problem I have is the second drop down is getting more than one of the same city. So for example if you select Greater Manchester in the drop down, it should return in the city drop down Manchester and Altringham, but it show manchester twice and altringham once, not sure why it is repeating the manchester one, as I am using select distinct? does any one have any idea why i get these results like this. Heere is the code for the drop down Code: [Select] <form action="quick-results.html" METHOD="POST"><p align="right">Quick Find: <select name="region" onchange="ajaxrequest('select2',this.value)"> <option value selected="">Choose your County</option><?php echo $options; ?></select> <select name="club_town" id="select2" class="userinput"><option value selected="">Choose your City</option></select><input type="submit" value="go"></form></p> Then we have two scripts and an ajax file. Here is the script that generates the first drop down: Code: [Select] <?php include("connect.php"); $sql = mysql_query("select distinct club_county from clubs ORDER BY club_county ASC"); $options = ""; while($row = mysql_fetch_row($sql)) { $options .= "<option value=\"$row[0]\">$row[0]</option>\n"; } $region = ""; $club_town = ""; if(isset($_POST)) { $region = $_POST["region"]; $club_town = $_POST["club_town"]; } ?> Here is the script for the second drop down that gets created based on the first Code: [Select] <?php include("connect.php"); $request = $_POST["request"]; $sql = mysql_query("select distinct club_town from clubs WHERE club_county = '".$request."' "); if (mysql_num_rows($sql) ==0) { echo ("<option selected>Choose your City</option>\n"); } else { $club_town = ""; while($row = mysql_fetch_row($sql)) { $club_town .= "<option value=\"$row[0]\">$row[0]</option>\n"; echo $club_town; } } ?> And finally here is the ajax file Code: [Select] function get_XmlHttp() { var xmlHttp = null; if (window.XMLHttpRequest) { xmlHttp = new XMLHttpRequest(); } else if (window.ActiveXObject) { xmlHttp = new ActiveXObject("Microsoft.XMLHTTP"); } return xmlHttp; } function ajaxrequest(tagID, post) { var http = get_XmlHttp(); var info = 'request=' + post; http.open("POST", 'inc/destinations.ajax.city.php', true); http.setRequestHeader("Content-type", "application/x-www-form-urlencoded"); http.send(info); http.onreadystatechange = function() { if (http.readyState == 4) { var mata = http.responseText.split("</option>"); for (i = 0; i <= (mata.length - 2); i++) { var container = document.getElementById(tagID); var newdiv = document.createElement("option"); if (i == 0) { container.innerHTML = ''; } newdiv.innerHTML = mata[i]; container.appendChild(newdiv); } } } } Help anyone?
