I'm new to JSP and this is quite confusing to me.
In Php I can do something like this :
<FORM METHOD="POST" ACTION="LoginFormAction.php">
<INPUT TYPE="TEXT" NAME="username" SIZE="16">
and then use this to get what was in the TextBox :
$_POST['username'];
The current equivalent I have in Jsp is :
<form action="checkLogin.jsp">
<input name="username" size=15 type="text" />
How can I get what is in the TextBox once I submit my form ?
You can just use: request.getParameter("username").toString()

UPDATE: per this response this is behavior of HTML5? I tried setting the parameters in hidden inputs and that works. Doesn't make much sense to me, but what do I know.
I have my form for a "next page" button set up like this:
<form id="next" method="get"
asp-controller="Search"
asp-action="Cities"
asp-route-sortOrder="#ViewData["CurrentSort"]"
asp-route-currentFilter="#ViewData["CurrentFilter"]"
asp-route-pageNumber="#(Model.PageIndex + 1)">
<input form="next" type="submit" class="page-btn" disabled="#nextDisabled" value="Next" />
</form>
When I inspect the page, the form has the correct action url (example):
/Search/Cities?currentFilter=Test&pageNumber=2
But the request actually being made is to
/Search/Cities?
But when it hits the controller, all of the parameters are null. Here is the top of my controller:
[Route("Search/Cities")]
public ActionResult Cities(string SearchString, string sortOrder, string currentFilter, int? pageNumber)
I'm not sure what I'm missing here.
you have 3 choices. This code was tested
first the most popular, you have to use post
<form id="next" method="post"
asp-controller="home"
asp-action="test"
asp-route-sortOrder="CurrentSort"
asp-route-currentFilter="CurrentFilter"
asp-route-pageNumber="1">
<label for="searchString">Search</label>
<input type="text" id="searchString" name="searchString"><br><br>
<input form="next" type="submit" class="page-btn" value="Next" />
</form>
in this case searchingString will be sent in a request body, all another params in a query string
second
<a href="/Home/Test?sortOrder=CurrentSort¤tFilter=CurrentFilter&pageNumber=2">
<button class="page-btn">Next</button>
</a>
the second option will generate get request if it is so important for you, but you will not be able post search string except using ajax.
third, you can use get, but route params should be in the inputs, probably hidden, search string will have a visible input
<form id="next" method="get"
asp-controller="home"
asp-action="test">
<input type="hidden" id="sortOrder" name="sortOrder" value="CurrentSort" />
<input type="hidden" id="currentFilter" name="currentFilter" value="CurrentFilter" />
<input type="hidden" id="pageNumber" name="pageNumber" value="23" />
<label for="searchString">Search</label>
<input type="text" id="searchString" name="searchString"><br><br>
<input form="next" type="submit" class="page-btn" value="Next" />
</form>
in this case nothing will be inside of the body, everything in a query string including searchString.
On a Typo3 website a form is integrated. The action should be routed to a typoscript user function.
This is what I tried so far:
The fluid form code (excerpt):
<form action="{f:cObject(typoscriptObjectPath: 'lib.mynlreg')}" method="post">
<input type="text" name="email" placeholder="Ihre E-Mail-Adresse">
<input type="submit" name="send" value="Jetzt registrieren" class="submit" />
</form>
The typoscript lib:
lib.mynlreg = USER_INT
lib.mynlreg {
userFunc = Vendor\Extension\myClass->myFunction
}
And the class:
class myClass {
public function myFunction($content, $conf) {
$arguments = $this->request->getArguments();
$formEmail = $arguments['email'];
return '<div>' . $formEmail . '</div>';
}
}
I expect to get the content of the form field "email", but after submitting the page throws an error. The question is, how do I get the post vars into the user function? Thank you for any help!
$this->request is not available in a userFunc. As gautamsinh mori says, you should use \TYPO3\CMS\Core\Utility\GeneralUtility::_GP('email');, however I'm not sure you understand what the f:cObject ViewHelper does.
With this code, your HTML before submitting the form will be:
<form action="<div></div>" method="post">
<input type="text" name="email" placeholder="Ihre E-Mail-Adresse">
<input type="submit" name="send" value="Jetzt registrieren" class="submit" />
</form>
Your HTML after submitting will be:
<form action="<div>filledInEmail</div>" method="post">
<input type="text" name="email" placeholder="Ihre E-Mail-Adresse">
<input type="submit" name="send" value="Jetzt registrieren" class="submit" />
</form>
I'd recommend making an extension for this, but if you really want/need to do it like this, I think what you're looking for is something like:
<f:cObject typoscriptObjectPath="lib.mynlreg" />
<form action="{uri.page(addQueryString: 1)}" method="post">
<input type="text" name="email" placeholder="Ihre E-Mail-Adresse">
<input type="submit" name="send" value="Jetzt registrieren" class="submit" />
</form>
This will create the form with action to the current page (including any query string). You then have to change the userFunc to return an empty string if the form hasn't been submitted. Something like:
class myClass {
public function myFunction($content, $conf) {
$formEmail = \TYPO3\CMS\Core\Utility\GeneralUtility::_GP('email');
if (empty($formEmail)) {
return '';
}
return '<div>' . $formEmail . '</div>';
}
}
I'm trying to insert a variable collected from a form into a URL, but I don't want the "?variable=value" part of the URL.
<form action="http://www.example.com/<?php echo htmlspecialchars($_GET['entry']);?>/" method="GET">
<input type="text" value="" name="entry" id="entry">
<input type='submit'>
</form>
Is there any easy way to do this? I want the browser to go to the following URL when the user types "whatever"
http://www.example.com/whatever/
Edit:
I've changed the code to the following, which seems to work, but have I now introduced a script vulnerability?
<form onSubmit=" location.href = 'https://www.example.com/' + document.getElementById('entry').value + '/' ; return false; ">
<input type="text" value="" name="entry" id="entry" placeholder="Your Promo Code">
<input name="promoSubmit" type="submit" value="Buy Now">
</form>
you could use javascript for this kind of tasks, i don't see why would you involve server side for such thing
but the easiest answer will be like:
<script>
function go(){
window.location='http://www.example.com/'+document.getElementById('url').value;
}
</script>
<input type='text' id='url'>
<button id='btn_go' onclick='javascript:go();'>Go</button>
In this form I want to get the value of the text box Enter Techs name: in to the URL but my form method is post.So that my url would look like
http://localhost/cs_3/index.php?page=chat&tech=
Is there any way I could do it.Can't use get method because I don't want the message to be seen in the URL.
<form method="post" >
<label>Enter Username:<input type="text" name="sender"/></label>
<?php if($user['Level'] == 3){?>
<label>Enter Clients name:<input type="text" name="tech"/></label>
<?php }else{ ?>
<label>Enter Techs name:<input type="text" name="tech" /></label>
<?php } ?>
<label>Enter Message:<textarea name="message" rows="8" cols="70"></textarea></label>
<div id="submit"><input type="submit" name="send" value="Send Message"></div>
</form>
You may use action param at your form.
Change it on key press in tech input by javascript (easy with jquery).
I need to merge these 2 forms into 1 so it passes the email address to all 3 sources.
Is it possible?
Form 1:
<form method="post" id="transparent_redirect_form" name="transparent_redirect_form" action="https://joinalpha.com/launch/signup.php/taster">
<input type="text" id="signup_email_address" name="signup_email_address" placeholder="you#business.com" />
<input type="submit" value="Subscribe" />
</form>
Form 2:
<form method="post" action="http://joinalpha.com/blog/signup/"><input type="hidden" name="ip" value="213.106.180.209" />
<input type="text" name="email" id="s2email" value="you#business.com" onfocus="if (this.value == 'you#business.com') {this.value = '';}" onblur="if (this.value == '') {this.value = 'you#business.com';}" />
<input type="submit" name="subscribe" value="Subscribe" />
</form>
Each form has only one field and one action - to send the email address somewhere...
Any clues how i do this?
I would suggest to use javascript.
Create a button or something outside of the form, then invoke the submit of the form, then use the DOM to change the action in the form, and call submit again.
