when i give an input field value as blackhat%%1985 and submit i get the post value as blackhat%85
the value is changed after require_once BASEPATH.'core/CodeIgniter.php';
<form action="" method="post" id="submitForm">
<input type="hidden" name="a" value="blackhat%%1985" />
<input type="submit" name="b" />
</form>
use urlencode() function for this.
You can use JavaScript's encodeURIComponent to encode the value before submitting the form.
encodeURIComponent('blackhat%%1985');
Of course, don't forget to decode it on the server-side after that.

I am programming in Spring and using Thymeleaf as my view, and am trying to create a form where users can update their profile. I have a profile page which lists the user's information (first name, last name, address, etc), and there is a link which says "edit profile". When that link is clicked it takes them to a form where they can edit their profile. The form consists of text fields that they can input, just like your standard registration form.
Everything works fine, but my question is, when that link is clicked, how do I add the user's information to the input fields so that it is already present, and that they only modify what they want to change instead of having to re-enter all the fields.
This should behave just like a standard "edit profile" page.
Here is a segment of my edit_profile.html page:
First Name:
Here is the view controller method that returns edit_profile.html page:
#RequestMapping(value = "/edit", method = RequestMethod.GET)
public String getEditProfilePage(Model model) {
model.addAttribute("currentUser", currentUser);
System.out.println("current user firstname: " + currentUser.getFirstname());
model.addAttribute("user", new User());
return "edit_profile";
}
currentUser.getFirstname() prints out the expected value, but I'm getting blank input values in the form.
Thanks.
Solved the problem by removing th:field altogether and instead using th:value to store the default value, and html name and id for the model's field. So name and id is acting like th:field.
I'm slightly confused, you're adding currentUser and a new'd user object to the model map.
But, if currentUser is the target object, you'd just do:
<input type="text" name="firstname" value="James" th:value="${currentUser.firstname}" />

I did not have a form with input elements but only a button that should call a specific Spring Controller method and submit an ID of an animal in a list (so I had a list of anmials already showing on my page). I struggled some time to figure out how to submit this id in the form. Here is my solution:
So I started having a form with just one input field (that I would change to a hidden field in the end). In this case of course the id would be empty after submitting the form.
<form action="#" th:action="#{/greeting}" th:object="${animal}" method="post">
<p>Id: <input type="text" th:field="*{id}" /></p>
<p><input type="submit" value="Submit" /> </p>
</form>
The following did not throw an error but neither did it submit the animalIAlreadyShownOnPage's ID.
<form action="#" th:action="#{/greeting}" th:object="${animal}" method="post">
<p>Id: <input type="text" th:value="${animalIAlreadyShownOnPage.id}" /></p>
<p><input type="submit" value="Submit" /> </p>
</form>
In another post user's recommended the "th:attr" attribute, but it didn't work either.
This finally worked - I simply added the name element ("id" is a String attribute in the Animal POJO).
<form action="#" th:action="#{/greeting}" th:object="${animal}" method="post">
<p>Id: <input type="text" th:value="${animalIAlreadyShownOnPage.id}" name="id" /></p>
<p><input type="submit" value="Submit" /> </p>
</form>
hi i want to change this url from get form
http://127.0.0.1:8000/allfiles?category_id=1&file_id=1
to this in laravel
http://127.0.0.1:8000/allfiles?filter[category_id]=1&filter[file_id]=1
how can i do that?
Actually i want change perquery=? to filter[perquery]=?
thanks
Try something like this in the blade (you can modify it if need):
<form action="http://127.0.0.1:8000/allfiles" method="GET">
<input name="filter['category_id']">
<input name="filter['file_id']">
<input type="submit">
</form>
I have a form and I want to set default value in the field below but it's not working.
<span>ID User:</span>
<input type="text" th:value="${session.name}" th:field="*{userid}" th:errorclass="field-error" />
</div>
<div>
<span class="name-in">ID Room:</span>
<input type="text" th:value="${id}" th:field="*{room}" th:errorclass="field-error" />
</div>
I read some topic about this problem and I try to change as given below
th:attr="value = ${session.name}"
But It's still not working. Field ID User is empty. I don't know how to solve this problem.
Although your question contain less information, but i think you want to put default value for all field. If you like to do so change
`<input type="text" th:value="${session.name}" th:field="*{userid}" th:errorclass="field-error" />`
to
<input type="text" name="userid" value="as your wish" th:errorclass="field-error" />
Instead of changing the html, you should instead set the value of *{userid} in your controller. That way you can keep your html the same:
// Controller
modelObject.setUserId(session.name);
// HTML
<input type="text" th:field="*{userid}" th:errorclass="field-error" />
I am trying to use laravel with polymer. I have built a form that looks like this
<form action="{{ url('settings/update') }}" method="post">
<input type="hidden" name="_token" value="{{ csrf_token() }}">
<h4>Choose your theme</h4>
<paper-radio-group selected="1">
<paper-radio-button name="1" label="Theme Default"></paper-radio-button><br/>
<paper-radio-button name="2" label="Theme Violet"></paper-radio-button><br/>
<paper-radio-button name="3" label="Theme Orange"></paper-radio-button><br/>
</paper-radio-group><br/>
<button type="submit" class="mui-btn mui-btn-primary">Change Theme</button>
</form>
But I have no idea how to retrieve those fields in my controller. Any help would be appreciated.
Form elements don't know how to work with custom elements like paper-radio-button. You could replace your form with ajax-form or use some JavaScript to handle the form submit event, gather up the values, and send the request yourself.
I am using jquery.validate 1.9 and wish to execute code every time the form automatically validates (using the default behavior).
I hoped there would exist an OnValidated event I could hook into, but can not find one.
After validation executes I wish to conditionally enable other parts of the page if the form is valid, and disable otherwise.
How would one go about adding a method call following the existing validate() function?
I'm using jquery validate 1.8.1, but you should still be able to accomplish this using the valid() function.
valid() will either validate the entire form if you pass it the form ID or individual fields if you pass their respective ID's. It will then return a Boolean based on if they are all valid or not.
Something like this should work:
<script type="text/javascript">
function tab1Validation(){
if($('#field1, #field2, #field3').valid()){
//Logic if all fields valid - eg: $('#NextTab').show();
}else{
//Logic if one or more is invalid
}
}
</script>
<form id="yourform">
<div>
<input type="text" id="field1" name="field1" />
<input type="text" id="field2" name="field2" />
<input type="text" id="field3" name="field3" />
</div>
<input name="nextTab" type="button" value="Next Tab" onClick="tab1Validation();" />
</form>
