I'm currently using Opencart which has a form in currency.tpl that changes the currency value depending on the button clicked.
The forms action works off of currency.php, there is then a button within the form that works as a drop down using data-toggle which allows the user to see the currencies available:
<form action="<?php echo $action; ?>" method="post" enctype="multipart/form-data" id="form-currency">
<button class="buttoninvis" style="font-size:14px; margin-top:-4px;" data-toggle="dropdown">
<?php echo $text_currency; ?></button>
My problem is that I am trying to have more than one action with a data-toggle button (which doesn't seem possible), the button which is currently opening a drop down menu, I would like it to still do this but also have another action which redirects to a different page when the button is clicked and the screen width is below X.
I have tried onclick, css displays, giving the button an ID and adding functions to detect the button click, etc but nothing works I'm not sure if it is to do with the form's action prohibiting it or the data toggle can only have one action?
Any help or ideas around this?

I am trying to figure out the best approach to modifying a hidden django form field. Or if it's even possible. I had my HTML setup to accomplish this very task and it was working perfectly. However, in order to prevent multiple submissions I had to change my HTML and now I am unable to figure out how to pass a value via an HTML button depending on what the user clicks on.
Previously, I had two buttons defined as outline below:
<button type="submit" class="button1" name="status" value="Saved"><h3 class="txtalgn4">Save</h3></button>
<button type="submit" class="button2" name="status" value="Submitted"><h3 class="txtalgn4">Submit</h3></button>
As stated above, this worked perfectly for the purpose of passing a value to an attribute for my model. The value of status was saved as expected depending on which button the user clicked on.
Now I have updated the buttons to type="button" in response to this issue that I opened up today...How To Prevent Double Submit With Form Validation
I tried using the following code:
<button type="button" class="button1" name="status" value="Saved"><h3 class="txtalgn4">Save</h3></button>
<button type="button" class="button2" name="status" value="Submitted"><h3 class="txtalgn4">Submit</h3></button>
And then I also changed the status field to {{ status.as_hidden }} in my HTML to get the value. This only works if I hardcode the status value in my database structure. I need to be able to get this value dynamically depending on what the user clicks. Is JQuery with Ajax the right approach for this? Is there some simple way to modify the hidden field depending on which button the user clicks?
Is there some better way to go about trying to get this field in a hidden manner? As stated above the HTML way with type="submit" worked perfectly, but caused problems when I was trying to prevent the user from double submitting the form. As in all things programming I solved one problem and created another.
Thanks in advance for any thoughts.
Keep using two submit buttons like you were. But instead of disabling the buttons, you disable the whole form from submitting if once submitted.
First, give your form a unique html ID.
<form id="myform">
...
</form>
<!-- JS code -->
<script type="text/javascript">
$('#myform').on('submit', function(e) {
if ($(this).hasClass('submitted')) {
// prevent submission
e.preventDefault();
return;
}
$(this).addClass('submitted');
});
</script>
I have a div result_head which is hidden by default. Whenever I click a button which will provide options to select results, this hidden div will display as a heading for the form.
<div class="result_head" id="result_head" style="display: none"> >Results</div>
And the form code
<form method="post" id="form_result">
<div class="form-group">
<-----some drop down menus here --------->
<div class="form-group">
<button type="submit" name="result_submit" id="result_submit" style="display: none;margin:1%;" >Submit</button>
</div>
</form>
After the submit and after the page refresh, I need to display the heading for the result.
I tried different methods to achieve without any luck.
Tried Adding onclick and onsubmit finctions along with form submit
<button type="submit" name="result_submit" id="result_submit" style="display: none;margin:1%;" onclick="document.getElementById('result_head').style.display = 'block';">Submit</button>
Tried to echo CSS in php to display_head.
<div class="result_head" id="result_head" style="display: none" <?php if (isset($_POST['result_submit'])){ echo 'style="display:block !important;"'; } ?> >Results</div>
Also found a method echo entire div via php after form submit which will create the new div after form submit. But that option is not feasible for me as I need to display the head before submit as well.
Also while looking into some solutions, found an option to change the button type from sumbit to button and use jquery\ajax to submit the form. I may have to change my entire code for that.
Is there any other way to do it ?
How about the following:
<div class="result_head" id="result_head" style="display: <?php echo ($_POST['result_submit'] ? 'block' : 'none') ?>">Results</div>
It just changes the style from none to block when submited.
after submitting form you can store value in localStorage for example
localStorage.setItem('isHeadingVisible', true);
and add code which will check in every page load is header visible or not by checking this
if(localStorage.get('isHeadingVisible')){}
you can read more about localStorage here
but this will not work if user will use another browser after these operations, because user's localStorage will be emty in new browser, so I would suggest to use backend data here, or check in every page load if localStorage.get('isHeadingVisible') is undefined and form is submitted, set localStorage.setItem('isHeadingVisible', true);
I have a PHP submit form, within that form I have a PHP image gallery that displays images from a folder. (I have a dropdown to select images from different folders).
When I click on an image from the gallery the path to that image is entered into an input field so it can be linked to the other information when submitted.
My problem is when I choose a different image gallery folder from the dropdown it submits the form. I understand why it does this, but am unsure how to change the way it uses PHP to choose different folders to JS/JQ so there is no need for a submit or refresh.
Here is the relevant code...
<script>
function change(){
document.getElementById("myfolders").submit();
}
</script>
$subF = $_POST['otherFolders'];
<form id="myfolders" method="post">
<select name="otherFolders" onchange="change()">
<option selected="selected">Other Galleries</option>
<?php
$otherFolders = $dirs2;
foreach($otherFolders as $item){
?>
<option value="<?php echo $item; ?>"><?php echo $item; ?></option>
<?php
}
?>
</select>
Thanks for any help
I believe that you dont want to refresh the page when a user clicks on submit. There is very limited info from the question, so I cannot provide changes to your code. But, what you want to do is either prevent the form from submitting by using the preventDefault(); function in JS and then reading the form elements, submitting an aJax request to your server (PHP), and using the server response to display on the page.
If you do not want the form to even submit, you can just make a button that does not submit a form, but simply has an onClick event that reads the form elements and does the same as above.
Form submit will always refresh the page if not prevented. If an action attribute is not provided, it will default to submitting the form to the current page.
EDIT 3: Ahha... some progress. The problem was actually in some code below the divs that I left out (updated HTML below to reflect). The second div contains a "required" input, so simply changing the div to display=none via javascript doesn't actually make the page entirely ignore the hidden Div. So a slight change to the angle of my question - how would I adjust the code below to completely ignore the hidden div, so that the required field is not read?
EDIT 2:I have tried removing the 2nd block of JS code below and inserting the dynamic PHP code directly into the input and div tags to change the display - still no luck.
EDIT 1: Just to confirm, the solution to a similar question doesn't work in this case: Auto checked radio buttons and php form processing - How to avoid blank field? it seems that the Chrome team have made changes in later versions that make this solution redundant.
A user on the website can select either Points or Stamps - I get the value from the Database via PHP and the form should have the relevant radio button checked and only show the Div related to that radio button.
Everything works fine, however, unless I manually change the radio button it will not let me POST the form i.e. I cannot post with value selected automatically from the DB - it seems a similar problem to this (Chrome Browser Ignoring AutoComplete=Off) - but no matter what I do with Chrome autocomplete it doesn't work. Also the page is recognising the radio as checked because it shows my dot in the right place. (EDIT 3: still unsure why this works in Mozilla but not Chrome - but latest Edits make this less important)
Heres my JS that shows the right Div if a radio button is changed:
$(function () {
var $divs = $('#option > div');
$('input[type=radio]').change(function() {
$divs.hide();
$divs.eq( $('input[type=radio]').index( this ) ).show();
});
});
This JS sets the correct radio button based on DB and shows the correct div when the page loads:
$(function() {
var $radios = $('input:radio[name=selection]');
var $type = "<?php echo $type; ?>";
if($type === 'points') {
$radios.filter('[value=points]').prop('checked', true);
document.getElementById('pointsdiv').style.display = 'block';
document.getElementById('stampdiv').style.display = 'none';
}
else if($type === 'stamp') {
$radios.filter('[value=stamp]').prop('checked', true);
document.getElementById('stampdiv').style.display = 'block';
document.getElementById('pointsdiv').style.display = 'none';
}
});
My HTML and PHP:
$type = $_SESSION['user']['type']; //Note: This is actually set at the very top of the page i.e. before the JS
<form autocomplete="off" action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]);?>" method="POST" role="form">
<input type="radio" id="selection" name="selection" value="points"></input><label>Points</label>
<input type="radio" id="selection" name="selection" value="stamp"></input><label>Stamps</label><br></br>
<div id="option">
<div id="pointsdiv">
//Points related information here
<input type="text" required="required"/>
</div>
<div id="stampdiv">
//Stamp related information here - below input is required so when pointsdiv is displayed, this entire div should not even load
<input type="text" required="required"/>
</div>
</div>
<button type="submit" class="button">Save</button>
</form>
Anyone have any ideas how I can load this page and post the form if I don't change the radio button - i.e. if it loads with "Points" checked and I click the Save button?
Input radio groups must have the same name but not the same id,
so you should change id="selection" for one of them.
If everything is in the same page and the page is in php,
then you have to wait for dom ready before setting input values.
There is a dynamic way without using javascript :
<input type="radio" <?=$type =='points'?='checked="checked"':''?> id="selection" name="selection" value="points">
The same thing you can do with the other radiobutton
and also with the divs pointsdiv and stampdivs
I'm trying to essentially have the submit button of search.htm be able to create a pop up with a text area which the users are required to enter a comment describing their actions and click the submit button in the pop up to effectively submit both forms to the same processing page. Both the forms in search.htm and frm_comment.htm will submit both sets of data back to search.htm which calls cfinclude on the server processing logic (server.htm).
In the below code I'm having the the "createPeriod" button submit everything that is in the "srch" form. It is also creating a pop up window which has a html textarea that allows the user to enter a comment. There is a reason that I need to split up the main form from the comment form (frm_comment.htm) but it's very specific to the task I'm trying to accomplish.
search.htm is structured roughly as such:
//include the template here to process the forms
<cfinclude template="../server.htm">
<cfform method = "post" action = "search.htm" name="srch" format="html">
<table>
//bunch of form fields here
.
.
.
.
//bunch of form fields here
<cfinput type="submit" name="createPeriod" value="Create"
onClick="ColdFusion.Window.create('comment', 'CommentBox',
'frm_comment.htm', {center:true,modal:true})">
</table>
</cfform>
I've tried to change the submit button in search.htm to just a cfinput type="button" because keeping it as a submit will make it so that the comment box will appear for a brief moment while the page reloads and disappear as soon as the page reloads. However, I was unable to preserve the form data from search.htm when changing the submit button to a regular button.
I've also tried to have my comment form's submit button's onClick function call a javascript function to submit both forms (to no avail) like so:
submitForms = function(){
document.forms["srch"].submit();
document.forms["srch1"].submit();
}
<cfinput type="button" name="submitComment" value="Submit" onClick="submitForms()"/>
Please advise on the best way to accomplish this task, sorry about the messy code.
This a very basic example, on how to have your 2 forms in one. The JavaScript will just show the comment form when the user clicks on "Search".
<!DOCTYPE html>
<html>
<head>
<style>
#hiddenStuff {
display: none;
}
</style>
</head>
<body>
<form action="...">
// search fields here
<input type="button" value="Search" onclick="document.getElementById('hiddenStuff').style.display='block';">
<div id="hiddenStuff">
// comment form stuff here
<input type="submit" value="Submit">
</div>
</form>
</body>
</html>
I also made a fiddle, if you want to see the result in action.
Sorry I'm not familiar with ColdFusion, but it shouldn't be too hard for you to translate :)
