4/14/2023 0 Comments Ajax php json decode example![]() ![]() (Is it possible to run php inside of JS?)Īny help accomplishing these results would anycodings_html be greatly appreciated. but I'm changing so many things based on what I'm seeing on other SO's and this page that I'm really in a daze. If error=three, run a php script that sets some session variables. I've tried multiple lines for the php, printr(POST), jsondecode(POST), etc. I have written anycodings_html some pseudo code below, but I don't know if anycodings_html or how I can do this in JS or AJAX. I want the JS anycodings_html to look at the $myJSON variable and decide anycodings_html what to do based on that. Now, the trouble I am having is back at the anycodings_html main page where the user is. While($row = mysqli_fetch_array($result)) $result = mysqli_query($connect, $query) ![]() $query = "SELECT * FROM users WHERE username = '$username'" I need to access my json inside the php file, retrieve some values, make some calculations. 3) what is the difference between filegetcontents & POST'json' EDIT: //BEGIN. Please let me know how to access the values from this json. $password = mysqli_real_escape_string($connect, $_POST) Shouldn't i use jsondecode 2) And even through the encoded json, i am not able to retrieve the values. $username = mysqli_real_escape_string($connect, $_POST) The PHP will anycodings_html look at the incoming data from the AJAX anycodings_html script, and then assign an error number to a anycodings_html JSON object depending on what is wrong with anycodings_html the credentials. JS/AJAX (Same page): function SubmitFormData() , I don't know anycodings_html how to have the AJAX call, decode the JSON, anycodings_html and then have some if statements that decide anycodings_html what to do based on the value of that JSON.īelow is the code I am using for the form. decode JSON string to PHP object, 2nd param sets to associative array. Store the parsed values in the variables for further processing before displaying them on the webpage. AJAX is used so that javascript can retrieve these JSON files when necessary, parse them, and perform one of the following operations. This script validates anycodings_html the data and then sets a JSON object to a anycodings_html number 1-3 based on what is wrong or right anycodings_html with the submitted credentials. I think I get it, 'I THINK', see in MVC if you do not set content-type to json, you won't be a happy person sending back json objects that map to models, but it also is possible to read it from Request. Any data that is updated using AJAX can be stored using the JSON format on the web server. When the anycodings_html users submits the data, AJAX passes it onto anycodings_html the submit.php script. I do anycodings_html not want the page to reload when the user anycodings_html submits the form, in case there is an error, anycodings_html and I need to seamlessly display an error anycodings_html message (Like wrong password).
