I have a site that I've put a lot of time and effort into and in the midst have also been using it to learn JavaScript. I'm pretty proficient at PHP so the site was mostly coded in PHP, but now I've decided it would be best use Ajax to update the mySQL database instead of PHP so my pages don't have to refresh every time a change is made.Are there any references that you know of that could help me out in the conversion process?Most of my PHP scripts POST back to themselves and I use if(isset($_POST)) to update the info on the mySQL database. I'm still a novice at JavaScript and Ajax.
I have managed to succesfully post the data to the php page... (i can see using firebug that it IS being sent) but i get a message Quote: Apache HTTP Server has encountered a problem and needs to close and the response is empty... what am i doing wrong?is possibly something to do with the space in the value of the options?
It's my first post/thread here, I haven't been active in forums for some time cause frankly I didn't need it, but this one just got me. I tried everything in my knowledge -and I mean everything, I'm a fanatic trial-and-error tester. Situation: jQuery, posts some data through Ajax collected primarily from a $('#textarea') to a php file on server. If the data is >X Bytes, I get 404 Not Found and the 404 Html page in Ajax error handler. Otherwise, everything runs smoothly and I get my results. I must specify that I post to a php file that loads Wordpress's wp-blog-header.php before doing calculations, as the code is intended to be part of a WPplugin.
I tried to return header("HTTP/1.1 200 OK") as some suggested, considering WP was altering the header for not finding the file as part of the system, and it solved the issue locally for some cases, but not remotly.
I tried to set the Content-Length in ajax call. I switched between the WP type of handling Ajax calls, and having my own .php file, in the folder of my plugin. Nothing worked, but trimming content. What could this be? post_data_size is 8M on server. Could this be maybe related to SSL as I've seen in some cases?
I have created some data(works php values no problems) and use it to fill some options. At the same time fill a javascript array from php input.Yeah it works on its own page.Problem when loaded into a div through ajax it doesn`t run javascript calls through page.
I have written a web page to create XML from user input. The user inputs a series of values, and these are turned into XML using javascript. The way I have done this is to load in a template XML file using an XMLHTTPrequest and append childNodes to it as required. Thus, what I end up with is a variable called "xmldoc" which is an XML document object. (If I do write(xmldoc) the answer I get is [object XMLDocument].)What I would like to do is to be able to save the thing as an xml file. To this end I have been trying to POST it to a php file that might do this, but to no avail; the php file does not seem to recognise it as an XML DOM object.
I have a table with dynamic html that contains drop down select lists and readonly text boxes. Dynamic calculations are done on change of a value in one of the drop down select lists.
For my first iteration the script works fine ( indicating that there are 33 form variables ). When trying another dropdown select value, the form elements.length is shown as 33 ( as about ) BUT the script then crashes with a 'null value' error. I cannot access any of the form variables - this works in all other browsers and platforms.
Here is what I am doing:Someone clicks 'add buyer' link on my pageIn a modal box, I load the form to add a buyer. The form is loaded via ajax and then fills the div containerwhen someone clicks the 'submit' button, it should then look at the value of the fields and post to a scriptCurrently I can't get jQuery to see node within the loaded AJAX.
take a look at the following form. Im calling <?php if (isset($_POST['submit])){echo "clicked";} but its not registering. The only difference is that this is the first time ive used the "image" type.
Have an html page with form data manipulate a MySQL database.i KNOW my html form and its data are correct so my problem lies within the JSP codehere it is.
Inputting fields works but i cannot delete, this code so things delete from the database properly?
statement.executeUpdate("DELETE FROM Members WHERE (clubMembers = '"memb"')"); statement.executeUpdate("DELETE FROM Members WHERE (MemberAddress = '"addr"')"); statement.executeUpdate("DELETE FROM Members WHERE (MemberTelephoneNumber = '"phon"')");
Is it possible that when I submit my form using the enter key, it would double post to the JSP where the action attribute is pointing to. I've been wracking my brains for hours how to trap it. Seems like my javascript that does the submit is doing it once but it's posting on the JSP twice.
Trying to pass variables from the javascript into my php script and into my SQL query so i can track the location of the iphone. So far i have...
<script type="text/javascript"> function getGPS() { if (navigator.geolocation) { navigator.geolocation.getCurrentPosition(showGPS, gpsError);
[Code].....
This gets the coordinates in javascript and the php runs and i get a new record in the database but it doesnt pass the variables from java to php. Anyone know a workaround to get the variables from the iphone to sql on a single page?
I want this to run in the background and refresh every now and then so i can track users location.
I have a 'to do' item in a page that has an ID attached to it. These items are stored in a database. When clicked I want to reverse the 'state' of the item (active to complete or complete to active) by updating the database using jquery & PHP.I think I almost have it. As all the values are collected ok and if I change the the page that writes to the database to GET and pass the data through the URL it updates the database fine.[code]
And my problem is when I use 'submit' button for first time on site jQuery seems to not get it and form is being posted as normal HTML form. Every next submition is posted using jQuery until I reload the site.
I need to provide the ability for a user to login and make a posting for announcements. I have done some searching and haven't really came up with anything that will work. I am using a script that is external to the web page that will display the message. My idea was to create a Div that contains a multi-line text box within it. I thought it might be possible to use innerHTML to post a message from a form to the web page that has this text box. Is this a good approach or is there a better way? I am trying to move away from using a CMS for this particular site.
I have a form and select menus. I am posting it ajax post method and loading the same page with load method as you see in codes. There is a random number genarator. I want to change this random number once a click submit. If i do not load the same page this number does not change. Therefore I use both post and load methods like in demo. However when i do like this there is a problem which is random number have been generated twice somtimes. If you click submit button successively you will see that the number on left top corner sometimes changes twice a click. Why it is so and how can i correct it.
I have an application with a button that opens up another website. That website requires credentials. I'm currently using window.open to get the url open and passing a variable to the end of the URL, but when I have searched for a good way to get the credentials passed by using post and can't seem to find a solution. I tried xmlhttprequest, but the limitation of cross-domains is huge because I will have external clients connecting to the database and don't think that asking them to lower the security settings in IE would be a good way to do it. All I need is the ability to click on the button, pass the username and password and have the url open to desired page. I posted the code of the application in another thread, but all I'm getting are just views.
From the user input I want to be able to take each of the text fields and format them into a table on the resumeProcessor.html. I however am unable to figure out how to call the values into my code.
