I tried to make secure PDF from HTML using MPDF.
All the guide I found is only to put password to PDF file so user without password can't open it.
I want to set these setting using MPDF
How do I set PDF security using MPDF but still allowing user to view the file?
Use mPDF method setProtection().
Its first parameter is an array of features you want to allow. If you pass an empty array:
$mpdf->setProtection(array());
none of available features will be allowed.
Possible names of the features are
copy
print
modify
annot-forms
fill-forms
extract
assemble
print-highres
Second parameter of the method is a password you would pass if you wanted the file to be password-protected.
After lots of search and no luck to found the solution.
I am validating a input file in laravel 4.2.*. Using the model validation rules but rules not working for me.
rules i am using in my model.php
'reqfile' => 'mimes:txt,pdf,doc,docx|max:20000'
and
'reqfile' => 'mimes:application/msword,application/vnd.openxmlformats-officedocument.wordprocessingml.document,text/plain,application/pdf|max:20000'
After applying these rules the validation errors generated but the errors also appear on the valid file selection.
Here's anybody tells me, where i am wrong to apply the rules.
Thanks in Advance.
For this validator rule to work you need to make sure that the value being validated for reqfile is an instance of:
Symfony\Component\HttpFoundation\File\File
or
Symfony\Component\HttpFoundation\File\UploadedFile
So if you're validating a form, reqfile must be a uploaded file. That means its value should come from Input::file(). So your validator should look something like this:
Validator::make(
// Value for reqfile
array('reqfile' => Input::file('reqfile')),
// Validator rule for reqfile
array('reqfile' => 'mimes:txt,pdf,doc,docx|max:20000')
);
The validation rule will actually try to guess the extension by extracting the mime type and compare that to the extension list passed into the rule. That means that you need to pass file extensions to the rule, not actual mime types, as the documentation clearly states:
The file under validation must have a MIME type corresponding to one of the listed extensions
this question might be a bit special. I am using this Joomla 2.5 extensions to give authors the abilty to add Attachments to articles: Joomla Attachments
The extension renders an input field called "description" in a backend form to insert an file description for the provided file. Unfortunately it´s not taking HTML tags which I need. By saving the form it seems a strip_tags() or preg_replace() or something similar cleans the input. I combed through the code of the attachments extension but couldn´t find a place where the input is cleaned or saved.
To hopefully stay in the Question + Answer rule of Stackoverflow:
Is there a class which extensions inherit from the Joomla Core to save form data to a DB-table ( which also could be responsible to clean and validate user input )?
thanks for any idea,
tony
You should see how the field is defined first:
1. Form definition
look into the
administrator/component/yourcomponent/models/forms/somename.xml
there you could find a form definition, if so it will also specify the field type: depending on the type there are several available filters; for example the default textarea will strip html, and you need to set
filter="raw"
in order to enable it. see http://docs.joomla.org/Standard_form_field_and_parameter_types for a list of fields, click and you can find the available format options.
2. model
If the model inherits from JModelAdmin or JModelForm or other JModel* it will automatically handle binding of the forms' data to the database, look for the Save function which should receive the form $data.
3. more
There are at least another dozen possibilities. If the above didn't help, try finding the form: possibly you could find it just by looking at the markup. Once you have the form, check the following fields:
option
task
view
This should help you find the php code that is invoked based on the form:
if view is set, maybe in ./views/someview/view.html.php you could find the saving logic.
if task is set, look for a function with the same name in ./controller.php
if task contains a ".", look for the controller in the ./controllers/ folder.
if option is not the name of your component, your component is sending the data to another component for saving, and most likely set a return-url
How to add extra fields in Joomla2.5 registration form? I am using profile plugin but i also want to change the order of the fields. Any Suggestion?
Copy the profile plugin and change it to do what you want, then install it and unpublish the old one.
You can add additional fields to the registration form by changing the database and a core component file.
First of all take a look of components\com_users\models\forms directory and there is a XML file called registration.xml. This is the file joomla creates the registration form fields. I hope you can understand this file and add what ever the necessary fields you want.
And after that check out your data base table called #__users and add the extra fields you want. (ex: if you want to add Telephone number add filed calld tp_no). And make sure to use the same name that you use in XML file "field name" for the database table column as well.
I imagine you are looking for something like this?
http://extensions.joomla.org/extensions/access-a-security/site-access/authentication/14303
Probably the safest solution in the short and long term. I've not used it but it looks like it does what you want and from an interface rather than changing hard code.
There is manual how do it. Turn on subtitles visit http://www.youtube.com/watch?v=a6xsKLiXF40
I'm using Spring 3 ability to upload a file. I would like to know the best way to validate that a file is of a certain type, specifically a csv file. I'm rather sure that checking the extension is useless and currently I am checking the content type of the file that is uploaded. I just ensure that it is of type "text/csv". And just to clarify this is a file uploaded by the client meaning I have no control of its origins.
I'm curious how Spring/the browser determines what the content type is? Is this the best/safest way to determine what kind of file has been uploaded? Can I ever be 100% certain?
UPDATE: Again I'm not wondering how to determine what the content type is of a file but how the content type gets determined. How does spring/the browser know that the content type is a "text/csv" based on the file uploaded?
You can use
org.springframework.web.multipart.commons.CommonsMultipartFile object.
it hasgetContentType(); method.
Look at the following example http://www.ioncannon.net/programming/975/spring-3-file-upload-example/
you can just add the simple test on CommonsMultipartFile object and redirect to error page if it the content type is incorrect.
So you can also count the number of commas in the file per line.There should normally be the same amount of commas on each line of the file for it to be a valid CSV file.
Why you don't just take the file name in you validator and split it, the file type is fileName.split("\.")[filename.length()-1] string
Ok, in this case i suggest you to use the Csvreader java library. You just have to check your csvreader object and that's all.
As far as I'm aware the getContentType(String) method gets its value from whatever the user agent tells it - so you're right to be wary as this can easily be spoofed.
For binary files you could check the magic number or use a library, such as mime-util or jMimeMagic. There's also Files.probeContentType(String) since Java 7 but it only works with files on disk and bugs have been reported on some OSes.
