I want to call PHP script that change some content of HTML file.
First, I have HTML with a button. When I click this button, it call a javascript function which will post some parameters to PHP script. This script will take the parameters and generate the content that will be displayed in the HTML.
1) First, I were have form tag that send post action to the php. I delete this form tag from the HTML.
2) Then, I call jsFunction() "javascript function" when clicking "Run" button in the HTML.
onclick="jsFunction();"
3) I create javascript function:
jsFunction(){
var url = "calculateResult.php";
var params = "querySeq=querySeq&program=program&patientIDarray=patientIDarray&blast_flag=blast_flag";
var xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function() {
if (xhttp.readyState == 4 && xhttp.status == 200) {
// change the content of the div in second tab
document.getElementById("result").innerHTML = xhttp.responseText;
}
};
xhttp.open("POST", url+"?"+params, true);
xhttp.send();
}
4) PHP file send replay to the javascript via echo statement.
Now, I think PHP does not receive any parameters from the javascript function!
Is there something wrong in my code?
Edit 1:
One of the steps in the php is generate text file and put one of the parameters "querySeq" in that file. When I open the file, it is empty.
The PHP file:

Edit 2:
I try the following for var params:
var params = 'querySeq='+querySeq+'&program='+program+'&patientIDarray='+patientIDarray+'&blast_flag='+blast_flag;
OR
var params = "querySeq=querySeq&program=program&patientIDarray=patientIDarray&blast_flag=blast_flag";
with
xhttp.open("POST", url, true);
xhttp.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded');
xhttp.send(params);
But, it does not works! The content in HTML does not changed.
It works only if I assign:
var params = "querySeq=querySeq&program=program&patientIDarray=patientIDarray&blast_flag=blast_flag";
with
xhttp.open("POST", url+"?"+params, true);
xhttp.send();
But, the received parameters are empty.
Any help please.
Thanks,
Edit 3:
It's working now. I did not pass parameters from HTML to JS file. Just by pass the parameters with onclick function
onclick=jsFunction(document.getElementById('some parameters').value)
Also I use:
var params = "querySeq="+querySeq+"&program="+program+"&patientIDarray="+patientIDarray
with
xhttp.open("POST", url, true);
xhttp.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded');
xhttp.send(params);
And it works!
Thanks everyone.
xhttp.open("POST", url+"?"+params, true);
xhttp.send();
You are making a POST request, implying that you are looking for the data in $_POST, but you have put all the data in the query string. It needs to go in the request body.
xhttp.open("POST", url, true);
xhr.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded');
xhttp.send(params);
PHP puts data from the query string in $_GET and data (with a recognised encoding) from the request body in $_POST. Unfortunately, it names the superglobal variables are the request methods where those places are commonly used to store data and not based on where the data actually is.
Working GET example:
<script>
function jsFunction() {
var url = "receive.php";
var params = "querySeq=querySeq&program=program&patientIDarray=patientIDarray&blast_flag=blast_flag";
var xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function() {
if (xhttp.readyState == 4 && xhttp.status == 200) {
// change the content of the div in second tab
document.getElementById("result").innerHTML = xhttp.responseText;
}
};
xhttp.open("GET", url+"?"+params, true);
xhttp.send();
}
</script>
Working POST example:
<script>
function jsFunction() {
var url = "receive.php";
var params = "querySeq=querySeq&program=program&patientIDarray=patientIDarray&blast_flag=blast_flag";
var xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function() {
if (xhttp.readyState == 4 && xhttp.status == 200) {
// change the content of the div in second tab
document.getElementById("result").innerHTML = xhttp.responseText;
}
};
xhttp.open("POST", url, true);
xhttp.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded');
xhttp.send(params);
}
</script>

What I am trying to do is to pass in variables from javascript to a php file using the url. The php is suppose to then parse the url into a json string and then store the json string on a separate text file. The php will then return the json string to the javascript for it to display. After a lot of testing I do believe my code isn't opening the php file or the php isn't parsing the url correctly.
here is the javascript:
var xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function() {
if (this.readyState == 4 && this.status == 200) {
obj = this.responseText;
var data = JSON.parse(obj);
alert(data);
txt += "<tr><th>Student Id</th><th>Student Name</th><th>Type</th></tr>";
for (x in data.student){
txt += "<tr><td>" + data.student[x].id + "</td>";
txt += "<td>" + data.student[x].lname + ", " + data.student[x].fname + "</td>";
txt += "<td>" + data.student[x].type + "</td></tr>";
}
document.getElementById("display").innerHTML = txt;
}
xhttp.open("GET", "assign13.php?type="+type+"&fname="+fname+"&lname="+lname+"&id="+id+"&fname2="+fname2+"&lname2="+lname2+"&id2="+id2, true);
xhttp.send();
alert("all done");
}
Here is the php file:
<?php
class student{
public $type;
public $fname;
public $lname;
public $id;
function setAll($type, $fname, $lname, $id){
$this->$fname = $fname;
$this->$type = $type;
$this->$lname = $lname;
$this->$id = $id;
}
}
$s1 = new student();
$s2 = new student();
$type = $_GET["type"];
$fname = $_GET["fname"];
$lname = $_GET["lname"];
$id = $_GET["id"];
$f2 = $_GET["fname2"];
$l2 = $_GET["lname2"];
$i2 = $_GET["id2"];
$s1->setAll($type, $fname, $lname, $id);
$s2->setAll($type, $f2, $l2, $i2);
if ($type == "duet"){
$directory = array($s1, $s2);
}
else{
$directory = array($s1);
}
$str = json_encode($directory);
file_put_contents("../data/data.txt", $str);
echo $str;
?>
You have errors on your php class, it should be like this.....
<?php
class student{
public $type;
public $fname;
public $lname;
public $id;
function setAll($type, $fname, $lname, $id){
$this->fname = $fname;

}

I'm constructing a survey and I have a textbox that generates dynamic dropdowns based on user input which displays the same data.
This is the script
<script>
function load_questions(){
var xmlhttp=new XMLHttpRequest();
xmlhttp.open("GET","ajax.php??main=1&subcategory="+document.getElementById("subcategorydd").value +"&cnt="+document.getElementById("q_num").value,false);
xmlhttp.send(null);
document.getElementById("question").innerHTML=xmlhttp.responseText;
}
function checkValues() {
_values = [];
$('.form-control-static').each(function() {
_values.push($(this).val());
//console.log($(this).val());
});
sameValue = false;
for ($i = 0; $i < (_values).length; $i++) {
for ($w = 0; $w < (_values).length; $w++) {
if (_values[$i] === _values[$w] && $i != $w) {
sameValue = true;
}
}
}
if (sameValue) {
alert('has the same value .');
return false;
}
alert('there is no the same value');
//do something .
}
</script>
This is the insert code when I'm creating the survey
<?php
$con = mysqli_connect("localhost","root","","imetrics");
if(isset($_POST['submit'])){
$title = $_POST['surveytitle'];
$catdd = $_POST['catdd'];
$subcatdd = $_POST['subcatdd'];
$gender = $_POST['gender'];
$age = $_POST['age'];
$occupation = $_POST['occupation'];
$occupationtwo = $_POST['occupdd'];
$relstatus = $_POST['relationshipstatus'];
$q_num = $_POST['q_num'];
$insert = mysqli_query($con, "INSERT INTO `surveyform` (`surveytitle`,`surveycategory`,`surveysubcategory`,`gender`,`age`,`occupation`,`occupation_status`,`status`) VALUES ('$title','$catdd','$subcatdd','$gender','$age','$occupation','$occupationtwo','$relstatus')");
if(!$insert){
echo mysqli_errno();
}
else{
$getMaxID = mysqli_query($con, "SELECT MAX(survey_id) as maxid FROM surveyform");
$row_2 = mysqli_fetch_array($getMaxID);
$survey_id = $row_2[0];
for( $a = 1; $a <= $q_num; $a++)
{
mysqli_query($con, "INSERT INTO surveyform_questions ( survey_id, question_id) VALUES ('$survey_id', ". $_POST['question_dropdowns'.$a] .")");
//echo "INSERT INTO surveyform_questions ( survey_id, question_id) VALUES ('$survey_id', ". $_POST['question_dropdowns'.$a] .")";
}
echo '<script language="javascript">';
echo 'alert("Survey Created!")';
echo '</script>';
}
}
?>
And this is my dropdown code
if($question !="" && $cnt!="" && $addQues!="yes" && $main != 1){
$i = 0;

while($row=mysqli_fetch_array($query))

echo $row["questiontitle"];
echo "</option>";
}
echo "</select>";
echo "<br />";

here's my submit button
<input type="submit" name="" id="btnSaveSurvey" class="form-control-static" onclick="checkValues();" value="check" />
What's the validation code that will prevent me from inserting if the data chosen from the dropdown is the same? For example I generated 2 dropdowns and I chose the same datas from the dropdown, what's the validation code for it?
Please call checkValues method your submit button click
<input type="submit" name="" id="btnSaveSurvey" class="form-control-static" onclick="checkValues();" value="check" />
checkValues method below :
function checkValues() {
_values = [];
$('.form-control-static').each(function() {
_values.push($(this).val());
//console.log($(this).val());
});
sameValue = false;
for ($i = 0; $i < (_values).length; $i++) {
for ($w = 0; $w < (_values).length; $w++) {
if (_values[$i] === _values[$w] && $i != $w) {
sameValue = true;
}
}
}
if (sameValue) {
alert('has the same value .');
return false;
}
alert('there is no the same value');
//do something .
}

I'm trying to use a PHP file to process serialized info from an Ajax request. I want to send back the value of each form field to be further manipulated by javascript (inserted into a div). The result is not being inserted into the HTML. When I alert the result I get {"return":["<p>form value for name<\/p>","<p>form value for description<\/p>"]} Any suggestions?
EDIT: Updated question with relevant HTML and revised PHP code.
HTML:
<div class="col-md-4">
<h5>Heading</h5>
<div id="formBasicResults"></div>
</div>
Javascript:
.on('success.form.fv', function (e) {
e.preventDefault();
var $form = $(e.target);
var bv = $form.data('formValidation');
$.post($form.attr('action'), $form.serialize())
.done(function (result) {
$('#formBasicResults').html(result.responseText);
alert(result);
},'json');
});
PHP:
if (!isset($_SESSION)) {
session_start();
if (!isset($_SESSION['token'])) {
$token = md5(uniqid(rand(), TRUE));
$_SESSION['token'] = $token;
$_SESSION['token_time'] = time();
} else {
$token = $_SESSION['token'];
}
}
foreach($_POST as $key = > $value) {
$temp = is_array($value) ? $value : trim($value);
$_SESSION[$key] = $temp;
}
$expected = array(
'name' = > 'string',
'description' = > 'string',
);
foreach($expected AS $key) {
if (!empty($_POST[$key])) {
$ {$key} = $_POST[$key];
} else {${$key} = NULL;
}
}
foreach($expected AS $key = > $type) {
if (empty($_POST[$key])) {
$ {$key} = NULL;
continue;
}
if (!isset($ {
$key})) {
$ {$key} = NULL;
}
}
function safe( $value ) {
htmlentities( $value, ENT_QUOTES, 'utf-8' );
return ($value);
}
$name = $_POST['name'];
$description = $_POST['description'];
$return['result']=array();
if(!empty($name)){$return['result'][]= '<p>' . safe($name) . '</p>';}
if(!empty($description)){$return['result'][]= '<p>' . safe($description) . '</p>';}
echo json_encode($return);
try something like this:
$('#formBasicResults').html(result['return'][0]);
or
$('#formBasicResults').html(result['return'][1]);
Instead of this:
if ($_POST['token'] == $_SESSION['token'])
{$return['return']=array();
if(!empty($_POST['name'])){$return['return'][] = '<p>' . htmlentities($_POST['name'], ENT_QUOTES, 'UTF-8') . '</p>';
if(!empty($_POST['description'])){$return['return'][] = '<p>' . htmlentities($_POST['description'], ENT_QUOTES, 'UTF-8') . '</p>';}
echo json_encode($return); }}
do this:
$return['responseText']='';
if ($_POST['token'] == $_SESSION['token'])
{
if(!empty($_POST['name'])){
$return['responseText'] .= '<p>' . htmlentities($_POST['name'], ENT_QUOTES, 'UTF-8') . '</p>';
if(!empty($_POST['description'])){
$return['responseText'] .= '<p>' . htmlentities($_POST['description'], ENT_QUOTES, 'UTF-8') . '</p>';}
}
}
echo json_encode($return);
I am having the following code:
var xmlhttp = new XMLHttpRequest();
xmlhttp.onreadystatechange = function()
{
if (xmlhttp.readyState === 4 && xmlhttp.status === 200)
{
result = xmlhttp.responseXML.getElementsByTagName("tr");
if(result)
console.log(result);
showTable(result);
isClicked = false;
}
}
xmlhttp.open("GET", "php_includes/getResult.php?search=" + document.getElementById("search").value, true);
xmlhttp.send();
my file will produce something like:
<tr><td>1</td><td>APPLES</td><td> 0000000000414</td><td>$0.79</td></tr>
<tr><td>2</td><td>Apple Sauce</td><td> 0000000000528</td><td>$1.92</td></tr>
<tr><td>3</td><td>Apple</td><td> 0000000000540</td><td>$0.59</td></tr>
<tr><td>4</td><td>Snapple</td><td> 0000000000543</td><td>$0.69</td></tr>
By running the code I get the following error:
"Uncaught TypeError: Cannot call method 'getElementsByTagName' of null"
However, when I use the xmlhttp.responseText it get the result. Any idea?
This is my PHP file:
$x = 1;
$count = 0;
$result2 = array();
$result .= "<search>";
while ($row = sqlsrv_fetch_array($stmt)) {
// $class = ($x % 2 !== 0) ? 'whiteBackground' : 'graybackground';
//echo "OOMAD INJA";
//$name = sqlsrv_get_field( $stmt, 0);
//echo "$i $name<br/>";
//setlocale(LC_MONETARY, 'en_US');
$plu = $row["F01"];
$result2[] = $row['F02'];
//$result .= "<tr class='$class' onclick = 'clicked($plu);' onmouseover='ChangeColor(this, true);' onmouseout='ChangeColor(this, false);' ><td>" . $x . "</td><td class='searchtable'>" . $row["F02"] . "</td><td> " . $row["F01"] . "</td><td height= '40px'>\$" . number_format((float) $row["F30"], 2, '.', '') . "</td></tr>";
$result .= "<tr1><td1>" . $x . "</td1><td2>" . htmlentities($row["F02"]) . "</td2><td3> " . $row["F01"] . "</td3><td4>\$" . number_format((float) $row["F30"], 2, '.', '') . "</td4></tr1>";
$x++;
}
$result .="</search>";
echo $result;
