I have a string that I would like to pass from JS to PHP via a hidden input, but the POST form does not return anything at arrival (I checked it with a var_dump($_POST)), which never happened to me at all.
Here is my HTML code:
<form action='' id='hash-form'>
<input type='hidden' id='hash' name='hash'/>
</form>
Here is my JS code for changing the value and submitting:
document.getElementById("hash").value = content;
console.log(document.getElementById("hash").value);
document.getElementById("hash-form").submit();
Thanks in advance!
The form lacks of the method attribute, thus it's GET by default, not post.
Add method="POST" into a form tag.
What is the default form HTTP method?

Below is my Javascript code where k and m are Javascript variables.
function javascriptfunction() {
document.forms[formname].action="gotopage.php?parameter1="+k+"¶meter2="+m;
document.forms[formname].submit();
}
The above code executes correctly when my HTML form has a POST method. Below is my HTML page:
<form name="formname" action=# method=POST>
<input type=text name="data1" value="one">
<input type=text name="data1" value="two">
<input type=button name="button1" value="send" onclick="javascritfunction();">
</form>
But when I give a GET method in my HTML form, then the HTML form data is submitted i.e
gotopage.php?data1=one&data2=two is submitting not Javascript action value i.e
gotopage.php?parameter1="+k+"¶meter2="+m
So how to submit the form with Javascript parameter when the method is GET in the HTML form?
Submitting a GET form will replace the query string in the action with the form data.
Put the data in hidden inputs instead.
In a GET request the form data has nowhere to 'go' other than in the query parameter string. So as Quentin points out, the query string gets automatically swapped out with the form field key value pairs. So you must use hidden fields to include extra data.
In a POST request you've also got the query parameter string available, if you want to use it, but the form data gets inserted into the request payload (which a GET request does not have), so does not interfere with the query string. That's why you can customise the action url with whatever query string you like.
I'm getting the error, "Invalid URL Exception" on submit of a button. I am assuming that this issue is coming from three form tags I have in the web page.
In the body, the first form tag is for "post" of the fields and redirection. The second one, which is inside of the first form tag, is for the search bar as part of company header.
The third one is a form class for the input fields, which is also inside the first form tag.
I tried placing an end form tag in the first line of my code, it closes the form tag which now looks like this:
<form method = "post" action="/sample/sampleweb.nsf/myForm?OpenForm&Seq=1" enctype="multipart/form-data" name=_myForm">
<input type="hidden" name="__Click" value="0">
</form>
Then the search form tag comes in after as also part of body. Upon clicking the submit button, I'm getting such error. When I tried searching by clicking the search, search functionality working as expected.
When I tried removing the form tag and end form tag for the search, and I click on Submit, it's working as expected.
I notice that domino is still creating end form tag at the last part of the page, right before the end of body tag. Could it be because of this?
To give you a better idea, here is the structure of it:
<html>
<body>
<form method = "post" action="/sample/sampleweb.nsf/myForm?OpenForm&Seq=1" enctype="multipart/form-data" name=_myForm">
<input type="hidden" name="__Click" value="0">
</form> //This comes out when I add end form tag in the first line of code.
<form class="searchbox">
<input id="searchtxt" class="searchbox-submit">
<input type="submit" class="searchbox-submit">
</form>
<form class="form-horizontal">
//Rest of the code go here having the input fields.
<button type="submit" onclick="return validatefields(event)">Submit</button>
</form>
</form> //This part is the generated form tag.
</body>
</html>
Any help would be appreciated.
Domino creates the form tags for you because it assumes you are doing data entry if the form is in edit mode. To prevent this use the setting on the form properties second tab (propeller head) for "On Web Access" "HTML". With that you can do anything you want in HTML but as Richard suggested you need to define where to go when the form is submitted.
Once created this way you need to use the ?ReadFrom url parameter rather than the ?OpenForm parameter
I have a simple form in a PHP application that I have to submit via POST method. Something like:
<form action="URL?page_id=10" method="POST">
<select name="some_name" id="some_id">
<option value='1'>...</option>
<option value='2'>...</option>
...
</select>
...
//submit button here
</form>
The goal is to go to the following URL on submit:
URL?page_id=10&selected_id=SELECTED_ID
where SELECTED_ID is the value chosen by the user from the select drop down menu in the form. I've done it by converting the whole form to post the parameters as GET as I need to have this SELECTED_ID visible in the URL. However, another requirement turned up saying that I need to pass everything through POST and still have the SELECTED_ID visible in the URL and now I'm looking for alternatives.
So the question gets down to: how can I add dynamically another GET parameter to the URL upon POST form submission with one of the values submitted with the form?
first you have to add a id to your form as below
<form id='form1' action="URL?page_id=10" method="POST">
then add call below function on your button click
function test(){
$('#form1').attr('action', $(this).attr('formaction')+'&selected_id='+$('#some_id').val());
}
use <form method="GET"> .. all the field values will be appended to the url automatically

send a value from javascript to html form input
having a value in javascript,
need to send that to
<'input type='hidden' id='imgscr'/>
when submitting the form the value also should submit..
(set value from javascript to html form input)
Your question is not very clear, but I think the answer is
document.getElementById('imgsrc').value = js_variable;
You might want to put this function in the forms onsubmit handler.
If you use jQuery, this is as easy as:
<form onsubmit="$('#imgscr').val('some value')">
You can substitute whatever you want for the value.
It is also possible to use the form notation if you set a name on your input field:
<form onsubmit="this.imgsrc.value='some value'">
<input type="hidden" name="imgsrc" id="imgsrc">
</form>
