i have set the form action to a text retrieved from the database which has an id.my problem is when the form action executed it always shows the first id even if i clicked on the text holding id=2.I have checked the page source and it's showing the correct id for all the text.
here is my view code
<?php foreach ($content as $cont):?>
<form id="offer" method="post" action="<?php echo base_url() . 'index.php/pages/detail'?>">
<input type='hidden' name='cont_id'id='cont_id' value='<?php echo $cont->id?>'>
<a onclick="document.getElementById('offer').submit();"><?php echo $cont->title?></a>
</br>
</form>
<?php endforeach;?>
</div>
<script>
function submitForm() {
document.getElementById("offer").submit();}
</script>
here is my controller :
echo $this->input->post('cont_id');
You can use .submit()
Submit
If you have JAVASCRIPT knowledge you can use the
document.getElementById("myForm").submit();
method to submit the form..
create a Javascript Function
<script>
function submitForm()
{
document.getElementById("myForm").submit();
}
</script>
use this code for the text you want to hyperlink the button to
<h1 onclick="submitForm()">Click on this text</h1>

I want to create a confirm yes/no box in php
my code like this:
<?php
if(isset($_REQUEST['id']))
{
?>
<script>
var cf=confirm("do you want to delete Y/N");
if(cf)
{ i want to call code edit of php
}
</script>
<?php
}
?>
<html>
<head>
</head>
<body>
<form name="frm" method="post" action="edit.php">
Edit <br>
Edit <br>
Edit <br>
</form>
</body>
</html>
I Want to when press Yes i call code edit in PHP
But it do not work.
Can you help me ?
Thanks you
Just use inline onclick event.
This is a simple techique, you can use it in your PHP page.
Edit
In your code, you have mentioned PHP but, have used JavaScript.
If you want to do a confirm with PHP,
Create an intermediate page for confirmation.
Post form data there.
On confirmation page, add two submit buttons:
Yes: If pressed this, redirect/post to edit page.
No: If pressed this, redirect back to form
So, your confirmation page should be:
<html>
<head>
</head>
<body>
<?php
if (isset($_POST['confirm'])) {
if ($_POST['confirm'] == 'Yes') {
header("Location:edit.php?id=1");
}
else if ($_POST['confirm'] == 'No') {
header("goBack.php");
}
}
?>
<form method="post">
<?php
if(isset($_REQUEST['id']))
{
?>
<input type="submit" name="confirm" value="Yes"><br/>
<input type="submit" name="confirm" value="No"><br/>
<?php
}
?>
</form>
Put an id on your form:
Create an event listener for the form's onsubmit event
<script>
function onFormSubmission(e){
return confirm("do you want to delete Y/N");
}
var frm = document.getElementById('frm');
frm.addEventListener("submit", onFormSubmission);
</script>
When the user submits a form they will be prompted with your message. If they click Yes the function will return true and the form will be submitted. Otherwise the function will return false and the form submission will be cancelled
I think this is what you want to do:
<?php
//YOU MUST BE SURE THAT YOUR URL CONTAINS THE $_REQUEST['id'] PARAMETER, OTHERWISE IT WON'T WORK FROM YOUR CODE... IF YOU WANT IT TO WORK REGARDLESS OF THAT, JUST COMMENT OUT THE IF(ISSET(... BLOCK...
$editURL = "edit.php"; //EDIT URL HERE
if(isset($_REQUEST['id'])) {
//ASSIGN THE ID TO A VARIABLE FOR BUILDING THE URL LATER IN JS...
//THE DEFAULT ID IS 1 BUT YOU CAN DECIDE WITH YOUR OWN LOGIC
$defaultID = ($dID = intval(trim($_REQUEST['id']))) ? $dID : 1;
?>
<script>
function confirmEdit(evt){
evt.preventDefault();
var cf=confirm("do you want to delete Y/N");
var id=<?php echo defaultID; ?>;
if(cf){
//i want to call code edit of php
//HERE'S THE CODE YOU MAY NEED TO RUN;
if(id){
//RETURN TRUE SO THAT THE SCRIPT WITH LINK TO THE APPROPRIATE URL
return true;
// OR REDIRECT WITH JAVASCRIPT TO EDIT PAGE WITH APPROPRIATE ID
//window.location = "" + <?php echo $editURL; ?> + "?id=" + id; //YOU ALREADY HAVE THE EDIT URL... JUST APPEND THE QUERY-STRING WITH ID TO USE IN THE EDIT PAGE
// You might also just (without redirecting) return true here so to that the page continues like you just clicked on the link itself...
}
}
}
</script>
<?php
}
?>
<html>
<head>
</head>
<body>
<!-- THE FORM TAG IS NOT NECESSARY IN THIS CASE SINCE YOUR ANCHOR TAGS HAVE THE EXACT URL YOU WANT ASSOCIATED WITH THEM... AND YOU DON'T EVEN NEED JAVASCRIPT IN THIS CASE... BECAUSE THE HREF OF THE LINKS ARE HARD-CODED... -->
<!-- <form name="frm" method="post" action="edit.php"> -->
<a class='class-4-css' onclick="confirmEdit();" id='dynamic-id-based-btn-1' href="edit.php?id=1">Edit Page 1 </a> <br>
<a class='class-4-css' onclick="confirmEdit();" id='dynamic-id-based-btn-2' href="edit.php?id=2">Edit Page 2</a> <br>
<a class='class-4-css' onclick="confirmEdit();" id='dynamic-id-based-btn-3' href="edit.php?id=3">Edit Page 3</a> <br>
<!-- </form> -->
</body>
</html>
So, now clicking on any of the Links will Ask me to confirm if I want to delete the Resource or not. If I choose yes, then the appropriate page is loaded for the Process...
not sure if the other answers really answered your question, this was my problem too, then I experimented and here's what I came up with:
.
confirmation in php :
$Confirmation = "<script> window.confirm('Your confirmation message here');
</script>";
echo $Confirmation;
if ($Confirmation == true) {
your code goes here
}
that's all, other people might look for this, you're welcome :)
I was looking to simply have a confirmation box in php before triggering POST isset without going through javascript:
echo "<input id='send_btn' type='submit' value='previous'
name='previous' OnClick=\"return confirm('Are you sure you want to go
to previous');\" >";
This appeared for me to be the easiest solution.
I have series of dropdown boxes which can be selected by the user. I then want to have two different submit buttons that will do two different actions with the selected data. I am trying to code the submit button to run the selected php, but when I click the button does nothing. Any help is appreciated, my code is below. AFAIK the only relevant bits are my formSubmit function and the input tag near the bottom of the code.
edit: I have edited out a bulk of the code and left the pieces that I think are relevant. Please let me know if more info is needed.
<!DOCTYPE html>
<?php
require 'config.php'; // Database connection
//////// End of connecting to database ////////
?>
<html>
<head>
<SCRIPT language="JavaScript">
//Scripts
function submitForm(action)
{
document.getElementById('f1').action = action;
document.getElementById('f1').submit();
}
</script>
</head>
<body>
<div>
<?Php
//Beginning of Form
echo "<form method=post name='f1' action =''>";
//Dropdown boxes are here
//This line is what is not working:
echo "<input type='submit' value='Careers' onclick=\"submitForm('rt.php')\">";
echo "</form>";
?>
</div>
</body>
</html>
Not quite sure what is wrong with the function, xe4me may have the correct answer. However, I just changed my onClick to this and it worked:
onClick=\"document.f1.action='rt.php'; document.f1.submit(); return true;\"
You're using document.getElementById('f1') in submitForm function
function submitForm(action)
{
document.getElementById('f1').action = action;
document.getElementById('f1').submit();
}
But your form doesn't have id attribute because of this line of code
echo "<form method=post name='f1' action =''>";
so the form won't be submitted when you click the Careers button. You need to add id='f1' attribute to the form by changing the above line of code to below
echo "<form id='f1' method='post' name='f1' action =''>";
Try the jQuery method :
http://api.jquery.com/jquery.post/
with
How to get ID of clicked element with jQuery
Whenever any button is clicked, find its id and based on that, use $.post to post data to the location you want.
you must add a class to your button and call the onclick based on that class name :
<?Php
....
echo "<input type='submit' class='submitter' data-action='rt.php' value='Careers' >";
echo "</form>";
?>
// In Javascript :
document.getElementByClassName('submitter').onclick = function(){
var action = this.data('action');
document.getElementById('f1').action = action;
document.getElementById('f1').submit();
}
I've done this so often before on different websites, but can't get it to work now.
I've got a simple form that posts perfectly well using a submit button, but for a specific reason I actually need it to submit via a url link instead. I'm using submit(). The form submits, but the data isn't posting.
What am I missing?
<html>
<body>
<?
if(isset($_POST['bar'])) { echo 'testing button<br>'; }
if(isset($_POST['information'])) {
echo $_POST['information'];
echo '</br>Info successfully posted.';
}
?>
<form action="test.php" method="post" id="fooform">
Hello World.<br>
Select checkbox: <input type="checkbox" id="information" name="information" value="yes">
<input type="submit" name="bar" value="Send"><br>
Confirm and Post<br>
Post Directly
</form>
<script type="text/javascript">
function SubmitForm(formId) {
var oForm = document.getElementById(formId);
alert("Submitting");
if (oForm) { oForm.submit(); }
else { alert("DEBUG - could not find element " + formId); }
}
</script>
</body>
</html>
The form starts to submit, then the href of the link is followed, and this cancels the form submission.
If you are using old-style onclick attributes, then return false; at the end to prevent the default action.
You would, however, be better off using a submit button (you are submitting a form). You can use CSS to change its appearance.
Try this code :
<html>
<body>
<?php
if (isset($_POST['bar'])) {
echo 'testing button<br>';
}
if (isset($_POST['information'])) {
echo $_POST['information'];
echo '</br>Info successfully posted.';
}
?>
<form action="test.php" method="post" id="fooform">
Hello World.<br>
Select checkbox: <input type="checkbox" id="information" name="information" value="yes">
<input type="submit" name="bar" value="Send"><br>
Confirm and Post<br>
Post Directly
</form>
<script type="text/javascript">
function SubmitForm(formId) {
var oForm = document.getElementById(formId);
alert("Submitting");
if (oForm) {
oForm.submit();
}
else {
alert("DEBUG - could not find element " + formId);
}
}
</script>
</body>
</html>
try to submit form with form id in jquery
<a class="submit">Post Directly </a>
$('a.submit').click(function(){
$('#fooform').submit();
})
Hiya:
i know some people would be so tired of my questions, but I'm working on a uni project and need to get it done as soon as possible. This question is about using JS on a button(button) and sending a php_my_sql update on the same button. The problem is JS uses button, right? but PHP uses button(submit). How can I get these two to work on one of these buttons, cuz there has to be only one button.
this is my code for JS
<script type="text/javascript">
function formAction(){
var x=document.getElementById("collect")
x.remove(x.selectedIndex)
}
</script>
HTML
<form method="post">
<select id="collect" name="Select1" style="width: 193px">
<option>guns</option>
<option>knife</option>
</select> <input type="**submit/button**" onclick="formAction()" name="Collect" value="Collect" /></form>
PHP
<?
if (isset($_POST['Collect'])) {
mysql_query("UPDATE Player SET score = score+10
WHERE name = 'Rob Jackson' AND rank = 'Lieutenant'");
}
?>
This can be a way
Submit the form through JS after removing parameter
<script type="text/javascript">
function formAction(){
var x=document.getElementById("collect")
x.remove(x.selectedIndex);
document.forms[0].submit();
}
</script>
Input type button
<input type="button" onclick="formAction()" name="Collect" value="Collect" />
Embed jQuery and use $.post() to send an AJAX request.
JavaScript can interact with the button whilst the user is navigating the page and entering data into the form. The instant the user pushes the submit button and the request for the form submission is sent JS no longer has control. The request is sent to the form's action (most likely a PHP file) which processes the request and gives an answer back.
If you really need to combine the two, look into AJAX.
<?php print_r($_POST); ?>
<script type="text/javascript">
function formAction(){
var x=document.getElementById("collect");
x.remove(x.selectedIndex);
submit_form();
}
function submit_form() {
document.form1.submit();
}
</script>
<form method="post" name='form1'>
<input type='hidden' name='Collect'/>
<select id="collect" name="Select1" style="width: 193px">
<option>guns</option>
<option>knife</option>
</select> <input type="button" onclick="formAction()" name="Collect" value="Collect" /></form>
<?
if (isset($_POST['Collect'])) {
//do whatever update you want
}
?>
Simple Solution
Make this modification in the form tag
<form method="post" onsubmit="return formAction()">
In JavaScript function add a line "return true;" at the end of the function.
Voila ..!!! you are done..!!
Enjoy..!!
Following on from a previous question, (previous question here), the problem I'm having seems to involve trying to pass/post a value through a form when the form action is '#'. I've tried session data but it always returns the last item from the database. Everthing else returns nothing.
Any help/ideas/advice greatly received, S. (Code below)
This is the code that displays the list of items, each containing an 'email' link/button to one instance of a popup window/form that is located at the bottom of the page.
<?php
$query = mysql_query("select * from istable where categoryID = '1'");
while ($result = mysql_fetch_array($query)) {
echo '<h4>'.$result['title'].'</h4>
<p>'.substr($result['descrip'],0,408).'... <strong>Read more</strong></p>
<form action="#" method="post" rel="#sheet" class="see">
<input type="hidden" name="propTitle" value="'.$propResult['title'].'">
<input type="submit" name="submit" value="Email">
</form>
';
}
?>
This is the code for the popup window/form at the bottom of the same page that is called through jquery.
<div id="sheet" class="rounded">
<!--{{{ pane1 -->
<div class="pane" id="pane1">
<h4>Email Details to a Friend</h4>
<p>You have selected to forward the details of <?php echo $_POST['propTitle']; ?> to a friend.</p>
<p>Please fill out the following form</p>
<form class="rounded" id="email-form" method="post" action="<?php echo $pageLink; ?>">
<!-- form goes in here -->
</form>
</div>
<!--}}}-->
</div>
<script type="text/javascript">
$(".see").overlay({mask: '#999', fixed: false}).bind("onBeforeClose", function(e) {
$(".error").hide();
});
</script>
Why are you using PHP for this? If the popup is called through the same page, use JavaScript to get the DOM element value and if you need to process data use AJAX.
