PHP inside html called by ajax did not work - javascript

So this is my ajax call
function insertModal(link)
{
$.ajax({
url: link,
cache: false,
dataType: "text",
success: function(data) {
$("#modalInput").html(data);
},
error: function (request, status, error) {
alert(request.responseText);
}
});
}
And this is my html file which called by ajax
<form>
<div class="modal-content">
<h3>Input Car</h3>
<div class="row">
<div class="col s12 select-container">
<i class="material-icons prefix light-green-text text-darken-1">date_range</i>
<select id="th_car_out">
<?php
include 'script/year.php';
?>
</select>
<label>Choose Car Year</label>
</div>
</div>
</div>
</form>
Everything is working good, the form show up etc, except the PHP script.
I already try changing my php script "include" to some basic php script echo "option" or even write simple echo "hi", but it still did not show anything.
Can anyone tell me what went wrong ?

Rename the file containing PHP code with the extension .php, as your web server is not configured to make PHP process *.html files.

are you shure that your file is with .php extension?
you can put html in your php file, but in html file is not possible to put php expression.

PHP and JQuery ajax url

I am using a ready booking form source code and I would like to make some changes according to our needs.
I quote below the source code that is important to be seen and not the whole source code of the file. I would like to execute, as soon as a button is clicked, a mysqli_query to update variables on the database. So, I am trying to use Jquery and AJAX to make this happen.
The code below shows a button Check Availability already defined which executes Javascript code and I added also my button "Book Now" and I would like to run also my code. See the code below:
<form id="bsSearchForm_<?php echo $_GET['index'];?>" action="<?php echo PJ_INSTALL_URL; ?>index.php?controller=pjFront&action=pjActionCheck" method="post" >
<div class="row ">
<div class="col-lg-6 col-md-6 col-sm-6 col-xs-6 col-xss-12">
<div class="form-group">
<label for="address">Pickup Address</label>
<input type="text" class="form-control" name="pickup" placeholder="Enter a location">
</div>
</div>
<div class="form-group pjBsFormActions">
<button type="submit" class="btn btn-primary"><?php echo("Check Availability"); ?></button>
<button type="submit" class="btn btn-primary" onclick="checkClicked()"><?php echo("Book Now"); ?></button>
</div><!-- /.form-group pjBsFormActions -->
</div>
</form>
Now at the same php file at the beginning I have defined this source code:
<script>
function checkClicked() {
$.ajax({
url: "test.php",
type: 'POST',
dataType: 'html'
});
}
</script>
So, I would like to run my own PHP source code at an external php file like test.php and get the input field data from "pickup" and perform a mysqli_query on database.
However the code at test.php file is not executed at all. I think that the problem is the form action parameter <?php echo PJ_INSTALL_URL; ?>index.php?controller=pjFront&action=pjActionCheck. How could I find this file(a lot of source files) and maybe place the source code there?
Or should I have to define the new button differently and so I would be able to call my own PHP file at any directory?
The AJAX URL parameter should be a relative or absolute path to the test.php file? Where should I create the test.php file at my directories?
Please help me find a quick solution to my issue.
This very easy and simple
1. Create an html page with the form like.
<form id="sample">
//some thing here....
<input type="submit" class="btn btn-success" name="submit" value="Create" id="sample">
</form>
2. Create an Js page like this.
//click function
$("#sample").click(function(event) {
sample();
});
//ajax function here
function sample(){
$.ajax({
url: '/path/to/file',
type: 'GET/POST',
dataType: 'default: Intelligent Guess (Other values: xml, json, script, or html)',
data: {
param1: 'value1'
},
success:function(result){
alert(result);
}
})
.done(function() {
console.log("success");
})
.fail(function() {
console.log("error");
})
.always(function() {
console.log("complete");
});
}
3. Create an php script file.
add the actual path in directory like if you are using the localhost example: public/script/test.php then the ajax path is ../script/test.php
4. the javascript link to the the html page like
example:
<script type="text/javascript" src="sample.js"></script>
you need to create test.php on same directory where your form's file is created.
If you have a submit-Button the form will be submitted with the action you defined and not with the onclick-event. For that to work you have to simply replace it with
<button type="button"

Update img with jquery and php

i'm trying to update img cover without refresh the page using ajax and php but it does not work at all
HTML
<div class="cover" >
<img id="b1" src="<?php echo $user->picture_path();>"class="cover"/>
<div id="modal-cover" class="cov-lo"> </div>
</div>
js
$('#b2').on({
'click': function(){
$('#b1').attr('src', <?php echo $user->picture_path();?> + '?' + new Date().getTime());}
});
the input and form
<form action="profile.php" method="POST" enctype="multipart/form-data" >
<div class="hio">
Upload <input type="file" onchange="this.form.submit()" name="cover" id="bla2"class="custom-file-input" />
</div>
</form>
Ajax would look more like this:
js/jQuery:
$(document).on({'click', '#b2', function(){
$.ajax({
type: 'post',
url: 'my_ajax_processor_file.php',
data: '',
success: function(data){
$('#b1').attr('src', data);
}
}); //END ajax
}); //END #b2.click
my_ajax_processor_file.php:
<?php
$dt = new Date().getTime();
$pp = 'get user picture path here';
echo $pp .' - '. $pp;
Note that you need to have an external PHP file, which I've called my_ajax_processor_file.php, that does some additional PHP processing and ECHOs back a value.
This value is received in the AJAX code block's success function, and called data (call it what you like - the name is set here: function(data).
Note that the contents of data variable are only available within that success function.
Here are some more basic examples of what AJAX looks like:
A simple example
More complicated example
Populate dropdown 2 based on selection in dropdown 1
I think you have a fundamental misunderstanding of where the PHP and HTML are interpreted:
PHP is a server-side scripting language designed for web development (see this Wikipedia article). That means that the PHP code is executed on the server before arriving in the browser.
HTML is interpreted as plain text by the browser. No PHP is executed in the browser.
Therefore, once the JS gets to the browser, echo $user->picture_path(); has already been executed and is interpreted as plain text by the browser.
Your JS will look like this once it hits the browser:
$('#b2').on({
'click': function() {
$('#b1').attr('src', '/the/path/to/the/picture' + '?' + new Date().getTime());
}
});

Call php file which return PDF with jQuery AJAX function

My php file: example_061.php create PDF return and everything works fine.
Now I want to call that file with jQuery AJAX to get this at my screen and I try:
$("#proba").click(function() {
//in here we can do the ajax after validating the field isn't empty.
$.ajax({
url: "tcpdf/examples/example_061.php",
type: "POST",
async: true,
data: {
ime: $("#ime").val(),
pozicija: $("#pozicija").val(),
jmbg: $("#jmbg").val()
}, //your form data to post goes here as a json object
dataType: "html",
success: function(response) {
window.open('example_061.pdf');
},
});
});
Everything is fine so success function work an I get alert message but I don't get PDF file as download or at screen. How I can do that?
You do not need to use AJAX to download a file. If the content-disposition header is set, it will be downloaded and the current page will not be reloaded.
Just add this to your php script that creates the PDF:
header('Content-Disposition: attachment; filename=' . $MyFileName);
And instead of AJAX, use a regular anchor tag link:
Download
As someone noted in the comments, if you need to post you can still use a simple form with the same effect:
<form method="POST" ACTION="tcpdf/examples/example_061.php">
<input type="hidden" name="myPostItem" value="My POSt VALUE" />
<input type="submit" value="download">
</form>

PHP Post to a div on main html page - So it can be parsed by Javascript

I have PHP code which successfully gets the contents of a directory on my server.
I wish to then write this array to a specific div on my main html page (so that I can parse this later and use this information further)
Currently my PHP navigates me away from my current page to write this array which I want to prevent.
Furthermore I wish to do all of the PHP work on a button click, and return the values on the main html page after.
How can I do this???
My button on my html page is as follows:
<form action="PHP_Function.php">
<input type="submit" class="learnButton" name="insert" value="Find Available Evidence" />
</form>
And my PHP code looks like this to carry out the work:
if (isset($_POST['action'])) {
switch ($_POST['action']) {
case 'insert':
insert();
break;
}}
I have an array: "IfPresentArray" which I then wish to write to my main html page:
if(in_array("Facebook.xml", $dirArray)){
$IfPresentArray[0]="1";
}else {
$IfPresentArray[0]="0";
}
Any help would be greatly appreciated as I am very new to PHP.
Thanks in advance
You need to use AJAX techniques to do this. Use a Javascript framework like jQuery to react to the button click, make a request to your PHP script, and then update the contents of the div.
See http://api.jquery.com/click/ for handling clicks, and http://api.jquery.com/jQuery.ajax/ for making the request.
Good luck!
You will need to use an ajax call. This allows your to click some div, send something to the server, receive a response and display an output in many different formats.
You can either reference the jQuery library in your header
<script src="//code.jquery.com/jquery-1.11.2.min.js"></script>
or just download it and save it whereever
Here is a basic ajax call:
<script>
$(document).ready(function(){
$('#someval').click(function(){
var content = $('#somecontenttoadd').val; //this could be many things... etc(.text, .html)
$.ajax({
type:'post',
url: 'PHP_Function.php',
data: 'action='+content,
success: function(resp){
$('#somediv').html(resp); //lets put the information into a div
//this could be anything response format like .val or .text instead of .html
},
error: function(e){
alert('Error: ' + e);
}
});
});
});
</script>
HTML -- you can get rid of the tags and just use the id of the object.
<input type="submit" class="learnButton" name="insert" value="Find Available Evidence" id="someval"/>
As others said, AJAX is the solution, I will give you the code that works for me, so that you have an exact starting point.
As I understand you have a separate html page and a php file that includes your function.
In order to make this work you will have to implement a function with an AJAX call.
This should be placed in a javascript file and will be invoked after the form submit button is clicked on the html page.
The AJAX call will then invoke your php function, get the response data back from php.
The javascript function will update the html page in the end.
You will need three files:
main.html
script.js
function.php
Let me replace my original answer with a full example of the three files.
main.html
<html>
<head>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js"></script>
<script src="/script.js"></script>
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.2/css/bootstrap.min.css">
</head>
<body>
<div class="container">
<form id="myForm" method="post" action="function.php">
<div class="form-group">
<label for="name">Name</label>
<input type="text" class="form-control" id="name" name="name" placeholder="Name">
</div>
</form>
<div class="modal-footer">
<button type="submit" form="myForm" class="btn btn-primary" id="SaveButton">Submit</button>
</div>
<div id="resultbox">
</div>
</div>
</body>
</html>
Here we included jQuery, our own javascript and bootstrap just to look better. the form action is our function.php, the form 'id' is used in our jQuery code. the "result box" box will display the response.
script.js
$(function(){
$("#myForm").submit(function(event) {
$.ajax({
type: "POST",
url: $(this).attr('action'),
data: $(this).serialize(),
dataType: 'json',
success: function(data)
{
//display data...
$("#resultbox").html(data.name).show;
}
});
return false;
});
});
this will override the default form submit behavior. I had a typo here in the original answer, I fixed it. url and data are taken from the html form, dataType is set to json, because we expect a json back.
function.php
<?php
echo json_encode(array('name' => $_POST['name']));
Our php code is just one line, we build an array and return it as json. You can then used in jQuery, just like any other json, as shown in the above code.

Passing HTML content through jQuery AJAX and PHP

I want to display the content of Division in one page to another.
<div id="box-cont" class="box-content">
<?php
echo $stat;// Contains multiple images with strings
?>
</div>
Here $stat will display multiple images with few contents. And i am using jQuery AJAX to display this html in another page.
var bcont = $('#box-cont').html();
$.ajax({
type:"POST",
url:"abc.php",
success: function(data) {
document.location.href='def.php?bcont='+bcont;
}
});
And i am getting this html in def.php as
$_GET['bcont'];
This is not working for me..
Thanks in advance
A shortcut method would be to use sessions to pass the html from one page to another.
<div id="box-cont" class="box-content">
<?php
echo $stat;
$_SESSION['stat'] = $stat; // make sure session_start(); is present on this page
?>
</div>
Then, in the success handler of your ajax call
$.ajax({
type:"POST",
url:"abc.php",
success: function(data) {
window.location.href='def.php';
}
});
Finally, in def.php
session_start();
echo $_SESSION['stat'];
Note: This is not an ideal approach but will do the job for you
Ok, you want to pass the html of #box-cont to def.php, right?
You're mixing post and get. Read: http://api.jquery.com/jquery.post/
and you'll find you need to use the data-parameter.
There's something odd with the success-part. You don't reload the frame/div
where def.php is sitting. What you've done is passing data to the server
but not getting anything back, (if I read your attempts correctly).
In fact there's currently little use for a server-via here, from what you
describe it can all be done at client / JS.
