how to post value of 3 input fields into database
Closed 9 years ago.
i have a java script function i want to post value of counter to my data base... how to do...this is a function to create 2 texbox and 1 select box on click... but whn i am applying another input tag to get and post counter value another input text box is getting reated... i dont want this i just want to post total value to counter whn submitt buttion is clicked
<script>
var counter=1;
function generateRow() {
var count="<font color='red'>"+counter+"</font>";
var temp ="<p> <div class='_25'><input type='textbox' id='textbox' name='stop"+counter+"' placeholder='Stop Name'></input></div> <div class='_25'><input type='textbox' id='textbox' name='timing"+counter+"' placeholder='Timing'></input></div> <div class='_25'><select id='ampm"+counter+"' name='ampm"+counter+"'><option>a.m</option><option>p.m</option></select> </div>";
var newdiv = document.createElement('div');
newdiv.innerHTML = temp + count;
var yourDiv = document.getElementById('div');
yourDiv.appendChild(newdiv);
counter++;
}
</script>
The absolute most basic way I can think of is:
Add an iframe somewhere in your page:
<iframe id="iframe"></iframe>
Create a php file counter.php
<?php
$counter = (int) $_GET['counter'];
$query = mysql_query('INSERT INTO table (counter) VALUES (' . $counter . ')');
// OR YOUR OWN QUERY TO DO THIS
?>
And add to your function the following javascript code:
document.getElementById('iframe').src = 'counter.php?counter=' + counter;
Obviously you can do it more complicated via ajax and read the json response etc but at its most basic level, this will suit you. Basically the trick is, you set the iframe source to the counter.php and pass the counter in a get parameter. When an iframe source is changed, it automatically loads, hence the server will then recieve the counter parameter and process it.
You can add display:none to the iframe to hide it visually.
Given the tags on the question:
Make an HTTP request (possibly using XMLHttpRequest) to a PHP handled URL that reads the data (likely from $_POST) and uses the PDO API to make an SQL query using that data.

How can i select the fragment after the '#' symbol in my URL using PHP?
The result that i want is "photo45".
This is an example URL:
http://example.com/site/gallery/1#photo45
If you want to get the value after the hash mark or anchor as shown in a user's browser: This isn't possible with "standard" HTTP as this value is never sent to the server (hence it won't be available in $_SERVER["REQUEST_URI"] or similar predefined variables). You would need some sort of JavaScript magic on the client side, e.g. to include this value as a POST parameter.
If it's only about parsing a known URL from whatever source, the answer by mck89 is perfectly fine though.
That part is called "fragment" and you can get it in this way:
$url=parse_url("http://example.com/site/gallery/1#photo45 ");
echo $url["fragment"]; //This variable contains the fragment
A) already have url with #hash in PHP? Easy! Just parse it out !
if( strpos( $url, "#" ) === false ) echo "NO HASH !";
else echo "HASH IS: #".explode( "#", $url )[1]; // arrays are indexed from 0
Or in "old" PHP you must pre-store the exploded to access the array:
$exploded_url = explode( "#", $url ); $exploded_url[1];
B) You want to get a #hash by sending a form to PHP? => Use some JavaScript MAGIC! (To pre-process the form)
var forms = document.getElementsByTagName('form'); //get all forms on the site
for (var i = 0; i < forms.length; i++) { //to each form...
forms[i].addEventListener( // add a "listener"
'submit', // for an on-submit "event"
function () { //add a submit pre-processing function:
var input_name = "fragment"; // name form will use to send the fragment
// Try search whether we already done this or not
// in current form, find every <input ... name="fragment" ...>
var hiddens = form.querySelectorAll('[name="' + input_name + '"]');
if (hiddens.length < 1) { // if not there yet
//create an extra input element
var hidden = document.createElement("input");
//set it to hidden so it doesn't break view
hidden.setAttribute('type', 'hidden');
//set a name to get by it in PHP
hidden.setAttribute('name', input_name);
this.appendChild(hidden); //append it to the current form
} else {
var hidden = hiddens[0]; // use an existing one if already there
}
//set a value of #HASH - EVERY TIME, so we get the MOST RECENT #hash :)
hidden.setAttribute('value', window.location.hash);
}
);
}
Depending on your form's method attribute you get this hash in PHP by:
$_GET['fragment'] or $_POST['fragment']
Possible returns: 1. ""[empty string] (no hash) 2. whole hash INCLUDING the #[hash] sign (because we've used the window.location.hash in JavaScript which just works that way :) )
C) You want to get the #hash in PHP JUST from requested URL?
YOU CAN'T !
...(not while considering regular HTTP requests)...
...Hope this helped :)
I've been searching for a workaround for this for a bit - and the only thing I have found is to use URL rewrites to read the "anchor". I found in the apache docs here http://httpd.apache.org/docs/2.2/rewrite/advanced.html the following...
By default, redirecting to an HTML anchor doesn't work, because mod_rewrite escapes the # character, turning it into %23.
This, in turn, breaks the redirection.
Solution: Use the [NE] flag on the RewriteRule. NE stands for No
Escape.
Discussion: This technique will of course also work with other special
characters that mod_rewrite, by default, URL-encodes.
It may have other caveats and what not ... but I think that at least doing something with the # on the server is possible.
You can't get the text after the hash mark. It is not sent to the server in a request.
I found this trick if you insist want the value with PHP.
split the anchor (#) value and get it with JavaScript, then store as cookie, after that get the cookie value with PHP
If you are wanting to dynamically grab the hash from URL, this should work:
https://stackoverflow.com/a/57368072/2062851
<script>
var hash = window.location.hash, //get the hash from url
cleanhash = hash.replace("#", ""); //remove the #
//alert(cleanhash);
</script>
<?php
$hash = "<script>document.writeln(cleanhash);</script>";
echo $hash;
?>
You can do it by a combination of javascript and php:
<div id="cont"></div>
And by the other side;
<script>
var h = window.location.hash;
var h1 = (win.substr(1));//string with no #
var q1 = '<input type="text" id="hash" name="hash" value="'+h1+'">';
setInterval(function(){
if(win1!="")
{
document.querySelector('#cont').innerHTML = q1;
} else alert("Something went wrong")
},1000);
</script>
Then, on form submit you can retrieve the value via $_POST['hash'] (set the form)
You need to parse the url first, so it goes like this:
$url = "https://www.example.com/profile#picture";
$fragment = parse_url($url,PHP_URL_FRAGMENT); //this variable holds the value - 'picture'
If you need to parse the actual url of the current browser, you need to request to call the server.
$url = $_SERVER["REQUEST_URI"];
$fragment = parse_url($url,PHP_URL_FRAGMENT); //this variable holds the value - 'picture'
Getting the data after the hashmark in a query string is simple. Here is an example used for when a client accesses a glossary of terms from a book. It takes the name anchor delivered (#tesla), and delivers the client to that term and highlights the term and its description in blue so its easy to see.
setup your strings with a div id, so the name anchor goes where its supposed to and the JavaScript can change the text colors
<div id="tesla">Tesla</div>
<div id="tesla1">An energy company</div>
Use JavaScript to do the heavy work, on the server side, inserted in your PHP page, or wherever..
<script src="http://code.jquery.com/jquery-1.9.1.min.js"></script>
I am launching the Java function automatically when the page is loaded.
<script>
$( document ).ready(function() {
get the anchor (#tesla) from the URL received by the server
var myhash1 = $(location).attr('hash'); //myhash1 == #tesla
trim the hash sign off of it
myhash1 = myhash1.substr(1) //myhash1 == tesla
I need to highlight the term and the description so I create a new var
var myhash2 = '1';
myhash2 = myhash1.concat(myhash2); //myhash2 == tesla1
Now I can manipulate the text color for the term and description
var elem = document.getElementById(myhash1);
elem.style.color = 'blue';
elem = document.getElementById(myhash2);
elem.style.color = 'blue';
});
</script>
This works. client clicks link on client side (example.com#tesla) and goes right to the term. the term and the description are highlighted in blue by JavaScript for quick reading .. all other entries left in black..
Im probably overlooking something very obvious but at this point i surrender and need help.
Here is my situation. When my page loads, in a while loops, PHP generates a table with data from my server. Each table row has a name column, phone, etc. One of the columns is an icon that when clicked allows the user to view a popup with notes on this particular lead. Easy stuff.
The icons in each row have the same class name and their ID's are unique.
I have an AJAX request that should be pulling the notes data from the server and displaying it in the popup when the user clicks on the relative icon. I am trying to use $('.class').click(this).attr('id'); to set a variable in my AJAX request with the id that needs to be submitted to my PHP script.
PROBLEM: The AJAX request and return seems to be working fine but no matter which row icon I click on it only displays the data that belongs to the first row, or the first instance with the class name 'homelead' Example: I click on row 1 icon and i get a popup with row 1's notes, GREAT!. I click on any other row and it only shows the 1st rows data, :(. I have confirmed that the ID's associated with each row icon are correct by doing a simple click.(this).(id) and alerting the id belonging to the row icon. All is correct, just can't seem to get the JS variable to update with the correct ID.
Im confused why this is. Any help would be appreciated. Here is my current code.
HTML:
<td>
<img class="homelead" id="<?php echo $leadsfetch['unit_id'];?>"
onclick="ajax_unitnotes();" src="images/list-view.png">
</td>
<?php echo "</tr>"; } ?>
AJAX request:
function ajax_unitnotes(){
var hr = new XMLHttpRequest();
var url = "PHP/getnotes.php";
// this variable should update with clicked rows id before submitting to PHP script
var unitidnotes = $('.homelead').click(this).attr('id');
var vars = "unitidnotes="+unitidnotes;
hr.open("POST", url, true);
hr.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
hr.onreadystatechange = function() {
if(hr.readyState == 4 && hr.status == 200) {
var return_data = hr.responseText;
document.getElementById("unitnotes").innerHTML = return_data;
}
}
hr.send(vars);
document.getElementById("unitnotes").innerHTML = "processing...";
}
As you are using an onclick trigger in the tag itself - which is usually un common when using jQuery. You can do this:
<img class="homelead" id="<?php echo $leadsfetch['unit_id'];?>"
onclick="ajax_unitnotes($(this));" src="images/list-view.png">
And the in your function
function ajax_unitnotes(e){
var unitidnotes = e.attr('id');
}
Your current code
var unitidnotes = $('.homelead').click(this).attr('id');
Actually does not know what it the this object you are trying to access.
Better yet you can use a jQuery event, remove the onclick from the img tag and have an event like this:
$('.homelead').click(function(){
id = $(this).attr('id');
});
You could pass the clicked object this to the function trigged by "onclick":
onclick="ajax_unitnotes(this);"
That will make the DOM object you clicked on available inside the JS function.
You need to change the function signature accordingly:
function ajax_unitnotes(clickedElement){
and then you can alter this
var unitidnotes = $('.homelead').click(this).attr('id');
to
var unitidnotes = clickedElement.id;
This will give you the value of $leadsfetch['unit_id'] = img id.
so I got this really simple jQuery datatable, and i'm trying to get my selected value into a php variable. Here is my code:
<script>
var hlr = 0; // Reference to the currently highlighted row
function rowClick()
{
if (hlr)
$("td:first", hlr).parent().children().each(function(){$(this).removeClass('markrow');});
hlr = this;
$("td:first", this).parent().children().each(function(){$(this).addClass('markrow');});
// You can pull the values out of the row here if required
var a = $("td:first", this).text();
var b = $("td:eq(1)", this).text();
//$_SESSION['Klantnaam']="+a+");
alert("Keuze = "+a+""); //this is what I need in my PHP session variable.
}
</script>
Thanks for reading, a response is highle appreciated.
I had already faced this question on my recent project
Here is my solution to you
But i had to take value in to session variable so
STEPS:
Created a php file which puts value to session variable
Send a ajax request to that php file with js var value
I have an admin page where I add and delete table rows on the fly.
The page comes loaded with the existent data in the database (mostly consisting in a sku_code and 5 different prices) but when I add rows on the fly, and fill them with the corresponding skus and prices, I want to save them as well in the database.
The problem is that what I do on the client-side with Javascript (add table rows on the fly) with innerHTML = '<input type="text"> is not accesible via $_POST variables of the main <form>
So basically i add via Javascript 's so i can fill them and save them as well in the database. But the $_POST values are empty.
Javascript code works fine. I have no clue where should i start debugging.
here's some Javascript code i'm using
function insert_record(){
var my_table = document.getElementById('my_table')
var tr = my_table.insertRow(my_table.rows.length-1)
//id-ul curent, numar toate row-urile - 1 (care este butonul OK)
var c_id = my_table.rows.length-2
tr.id = 'row_' + c_id + ''
var tr_td_1 = tr.insertCell(0)
tr_td_1.className = 'text2'
tr_td_1.align = 'center'
tr_td_1.innerHTML = 'SKU'
var tr_td_2 = tr.insertCell(1)
tr_td_2.className = 'text3'
tr_td_2.width = '63'
tr_td_2.innerHTML = '<input name="sku_' + c_id + '" type="text" id="sku_' + c_id + '" size="33" value="">'
....this addes a inside the table just before the last which contains the submit button, after which there's the
You need to assign a label to element. Then you can grab it in next page.
Instead of innerHTML = <input type="text"> try to use
<script>
function addElement(tag_type, target, parameters) {
//Create element
var newElement = document.createElement(tag_type);
//Add parameters
if (typeof parameters != 'undefined') {
for (parameter_name in parameters) {
newElement.setAttribute(parameter_name, parameters[parameter_name]);
}
}
//Append element to target
document.getElementById(target).appendChild(newElement);
}
</script>
You can call this function below either click of even or manually addElement('INPUT','targetTag',{id:'my_input_tag', name:'my_input_tag', type:'text', size:'5'});
you should give the name attribute. if you are worried about the unlimited numbers of fields just go for the array of the input variables,
like this
<input type="text" name="field1[]">
Now you can access them in post like this:
$_POST['field1'] //this is an array of fields
EDIT:
First thing is that you should use some library like jquery which eases the work.
I suggest you make sure your all your fields are inside the form and that you have named all of them instead of trying ajax or functions like #shail suggested.
In my opinion they are not solving the problem, just avoiding it.
I'm having problem trying to request new page(s) from CodeIgniter using JQuery Ajax and open them in a new blank page
The following is the example scenario of current code which is working,
1.) User select the customer's receipt by checkbox
<input type='checkbox' class='customer_id' value='<?php echo $entry->customer_id;?>'>
2.) Javascript read the customer(s) id then send those data to CodeIgniter. Once return data is received, fire callback function to display them target div
var data;
var counter = 1;
$(.customer_id:checked).each(function(){
data['customer_' + counter] = $(this).val();
})
$.post('finance/getReceipt', data, function(){
$('#some_target_div').html(data);
}
3.) CodeIgniter retrieve customer data from db and generate page
function getReceipt(){
$counter = 1;
while ($this->input->post('customer_' + $counter)){
$where['customer_id'] = $this->input->post('customer_' + $counter);
$data += $this->getCustomerReciept($where);
}
$this->load->page('finance/receipt', $data);
}
But now I need to convert this code to make it open a new blank page with a print button
The purpose of this is because I want to generate a formatted receipt and display in a new blank page with a print button. I know that there are several plugin that I can print a div but this is the request from my client. So, that's isn't a solution for me.
Any suggestion or comment will be great. Thank in advance.
I think the easiest way would be to create an auxiliar form to post your data to a new page instead of using $.post So, this would be the code:
var data;
var counter = 1;
$(.customer_id:checked).each(function(){
data['customer_' + counter] = $(this).val();
});
$('<form action="finance/getReceipt" method="POST" target="_blank" style="display:none">' +
'<input type="hidden" name="data1" value="value-data1" />'
).appendTo("body").submit().remove();
Just change your data1 param to the one you want, or add more if you want.
And that's it. The magic is in using a _blank target for the form.
Hope this helps. Cheers
PS: The other way would be creating a new window with window.open and assign its content with javascript.
