I have a registration form that need to upload image as profile image during registration, I want to remove this uploading field from registration form as the user can upload it later but the problem is the registration form is connected to image process so the field can not be empty, this is the code for store propose inside registration controller:
public function store(RegisterUserRequest $request)
{
$newUserProfileImagePath = $profileImagePath = App::make('ProcessImage')->execute($request->file('profileimage'), 'images/profileimages/', 180, 180);
$newUserBirthday = Carbon::createFromDate($request->year, $request->month, $request->day);
$newUser = $this->dispatchFrom(RegisterUserCommand::class, $request, [
'birthday' => $newUserBirthday,
'profileImagePath' => $newUserProfileImagePath
]);
return redirect()->route('feeds_path');
}
How can I give a default value or disconnect it from image process?
You can set value like this:
$newUserProfileImagePath = $profileImagePath = "any image path";
OR you can try to remove All things about file uploading from this method and from this class "RegisterUserCommand. and after this you are still facing error then please upload "RegisterUserCommand" class. I will give you more instructions.
Happy Coding!

Within Laravel, I am successfully able to have a user upload a file on a page, but I want to know if there is a way for there to be an error displayed to that user before they submit the page that the file is too big. Something like "The file you selected to upload is 25MB. Get it below 20MB."
Is there some kind of package that can handle this?
Validating the file size on client side. (Mentioning this because you have mentioned that you would like to alert the error before form submit.)
Check the example code below which uses jQuery :
$(document).ready(function() {
$('input[type="file"]').change(function(event) {
var fileSize = this.files[0].size;
var maxAllowedSize = //add your value here;
// check the file size if its greater than your requirement
if(size > maxAllowedSize){
alert('Please upload a smaller file');
this.val('');
}
});
});
Validation on server side(you can change mime types as per the file type you want to allow) :
<?php
public function store(Request $request){
$request->validate([
'file_input_name' => 'file|max:25000|mimes:jpeg,bmp,png',
// add validations for other fields here
]);
}
For more check documentation
You don't need a package to do this, you can create either a Request class or use a validator:
1. Create a Request class:
Run the command php artisan make:request FileRequest
Then, on the File generated under App\Http\Requests\FileRequest do the following:
Change the authorize method to return true instead of false.
Under the rules method you return your validation rules:
return [
"file_input" => "max:20480", //If your input type's file name is "file_input"
];
According to documentation, max rule verifies that the input size from the user will not exceed the specified number in kilobytes for files.
2. You can also create a validator in your controller method:
use Validator;
public function store(Request $request)
{
$validator = Validator::make($request->only('file_input'), [
'file_input' => 'max:20480',
]);
if ($validator->fails()) {
return redirect()
->route('your.route.name')
->withErrors($validator)
->withInput();
}
// other code here
}
I have a single input field (using select2 plugin) in a blog post form which allow user to insert post tags from existing tags in the table or create new ones and store them in the Tag table and also attach them to the post when they hit submit post button. I've managed to get this work by filtering the input with array_filter(), if the input is !is_numeric the input will first get stored in Tag table and then attach the id to the post.
The problem with this is that it's not working when the new tag from the input is in full numeric type, like 2017 tag. Is there a solution to get this working so the new tag is not limited to string only but also numeric type ? and if possible, I don't want to use any package for this.
The post store method :
public function store(PostsReq $request) {
$input = $request->all();
$post = Post::create($input);
//Handle the tags
$getTags = $request->input('tagspivot');
$oldTags = array_filter($getTags, 'is_numeric');
$newTags = array_filter($getTags, function($item) {
return !is_numeric($item);
});
foreach ($newTags as $newTag) {
if ($tag = Tag::create(['title' => strtolower(trim($newTag))])) {
$oldTags[] = $tag->id;
}
}
$post->tags()->attach($oldTags);
// Upload Image
if ($request->hasFile('image')) {
$input['image'] = $this->uploadImage($request, $post);
}
return redirect()->route('postindex')->with($this->postStoreSuccess);
}
Here is three lines of code would be more than enough:
$tag = Tag::firstOrCreate([
'title' => $request->input('tagspivot'),
]);
You don't need to check for !is_numeric. However, in your form don't use tag id as value. use the title.
I have a generic Image model that is linked to by other models that need to have images attached. In most places the image is not required and we have fallbacks in case there is no image uploaded, but in a few particular cases I need to force the upload of an image for the form to validate, but I'm not sure how to validate that through another model. For instance, my model is something like this:
class Person extends AppModel
{
public $belongsTo = array(
'Image' => array(
'className' => 'Image',
'foreignKey' => 'image_id',
'type' => 'LEFT',
)
);
public $validate = array(
...
);
}
The Person model contains some text fields that folks have to enter as well as a redirect_url field. If a redirect is set the page logic will skip trying to load anything and will redirect directly to that URL. But, if it is not set then a bunch of other fields are required. I've got this working properly using a custom validation method in my Person model, but image_id field is not explicitly checked by the Person model since it is just a pointer to the Image model.
Can I somehow add a custom/dynamic validation rule to Image in this instance to have it check if Person.redirect_url is set? The only thing I can figure to do is to add this to my beforeSave() and basically manually check it using $this->data but I'd like to do this the "right" way if it's possible, hooking into the Validation class.
I tried a few variations on using something like this, with no luck thus far:
$this->Person->Image->validate['id']=array(...);
Edit:
Here is what I've tried doing, which kind of works:
public function beforeValidate($options=array()) {
parent::beforeValidate($options);
if(empty($this->data['redirect_url'])) {
if (!isset($this->data['Image']['filepath']) {
$this->invalidate('Image.filepath', 'Custom error message.');
return false;
}
}
}
This lets me invalidate the field without having to add extra code elsewhere, but when printing out the form field on the front end, I end up getting a generic "This file is required" error instead of my "Custom error message". I think this might be because file uploads are handled by a plugin that spirits them away to S3 instead of the local filesystem and it's getting overridden somewhere up the chain.
I'm working on Zend Framework 1.11.12 version. In my add form where we've to put file upload (for photo upload) field and it has few validations as required, file extensions and size specific criteria mentioned as below, which is declared under my zend form:
// part of my form class (Default_Form_Photo::init)
$photo = new Zend_Form_Element_File('photo', '', array('required' => true));
$photo->setLabel('Photo')
->setDestination('/var/www/zendframework/public/uploads/');
// ensure its mandatory
#$photo->addValidator('required', true);
// ensure only one file
$photo->addValidator('Count', false, array('min' => 1));
// max 2MB
$photo->addValidator('Size', false, 2097152)
->setMaxFileSize(2097152);
// only JPEG, PNG, or GIF
$photo->addValidator('Extension', false, 'jpg,jpeg,png,gif');
$photo->setValueDisabled(true);
$this->addElement($photo, 'photo');
Now I have taken a hidden field, for edit page which will return me current image name, if no new image uploaded:
// hidden element for edit time photo save
$this->addElement('hidden', 'photo_uploaded', array( ));
I set this hidden element value from controller by $form->photo_uploaded->setValue($result['photo']).
Now the problem is: when user edit information, it does not allow saving because the file upload field is blank as no new image uploaded, but in my case have to use existing current image, which I am passing from hidden element to my controller.
So validation causes problem here, any idea how can i remove validation for my edit page where users do not have to upload new image every time, they are editing information.
Earliest response will be appreciated.
Thanks !
The answer to this requires you to add two functions to your form: isValid and getValues. First of all, remove required from the photo element as we are going to check for this in isValid:
/**
* Check if a photo has been submitted. If not, set the form element as required.
* #param $data Array of values
* #return Boolean true if all form element requirements are mets
*/
public function isValid($data)
{
//A photo has not been uploaded this time, nor previously.
if(!$data['photo'] AND !$data['photo_uploaded'])
{
$this->photo->isRequired(TRUE);
}
return parent::isValid($data);
}
/**
* Return an array of form element values
* #return Array of values
*/
public function getValues()
{
$values = $this->getValues();
//if photo has been uploaded, but no previous photos have been uploaded, then set photo_uploaded value.
if($values['photo'] AND !$values['photo_uploaded'])
{
$values['photo_uploaded'] = $values['photo'];
}
//if previous photo has been uploaded, but photo has not been uploaded this time, set photo value
if($values['photo_uploaded'] AND !$values['photo'])
{
$values['photo'] = $values['photo_uploaded'];
}
return $values;
}
I'm building an admin utility for adding a bulk of images to an app I'm working on. I also need to to log certain properties that are associated with the images and then store it all into the database.
So basically the script looks into a folder, compares the contents of the folder to records in the database. All of the info must be entered in order for the database record to be complete, hence the form validation.
The validation is working, when there are no values entered it prompts the entry of the missing fields. However it happens even when the fields ARE filled.
I'm doing something a bit funny which may be the reason.
Because I'm adding a bulk of images I'm creating the data within a for loop and adding the validation rules within the same for loop.
Here is the results:
http://s75151.gridserver.com/CI_staging/index.php/admin_panel/bulk_emo_update
Right now I have default test values in the form while testing validation. The submit button is way at the bottom. I'm printing POST variable for testing purposes.
Here is the code:
function bulk_emo_update() {
$img_folder_location = 'img/moodtracker/emos/';//set an image path
$emo_files = $this->mood_model->get_emo_images('*.{png,jpg,jpeg,gif}', $img_folder_location); //grab files from folder
$emo_records = $this->mood_model->get_all_emos(); //grab records from db
$i=1; //sets a counter to be referenced in the form
$temp_emo_info = array(); //temp vairable for holding emo data that will be sent to the form
//loop through all the files in the designated folder
foreach($emo_files as $file) {
$file_path = $img_folder_location.$file;//builds the path out of the flder location and the file name
//loops through all the database reocrds for the pupose of checking to see if the image file is preasent in the record
foreach($emo_records as $record) {
//compairs file paths, if they are the
if($record->picture_url != $file_path) {
//FORM VALIDATION STUFF:
$rules['segment_radio['.$i.']'] = "required";
$rules['emo_name_text_feild['.$i.']'] = "required";
//populating the temp array which will be used to construct the form
$temp_emo_info[$i]['path'] = $file_path;
$temp_emo_info[$i]['name'] = $file;
}
}
$i++;
}
//sets the reference to validation rules
$this->validation->set_rules($rules);
//checks to see if the form has all it's required fields
if ($this->validation->run() == FALSE) { //if validation fails:
print_r($_POST);
//prepairs the data array to pass into the view to build the form
$data['title'] = 'Bulk Emo Update';
$data['intro_text'] = 'fill out all fields below. hit submit when finished';
$data['emos_info'] = $temp_emo_info;
$this->load->view('admin_bulk_emo_update_view',$data);
} else { // if it succeeds:
//printing for test purposes
print_r($_POST);
$this->load->view('form_result');
}
}
I'm new to codeigniter and php in general so if anything looks outrageously weird please tell me, don't worry about my feelings I've got thick skin.
if ($this->validation->run() == FALSE)
if you are calling the run() method of the validation class every time the script is run, will it ever return TRUE and run the else? Maybe a different return?
I'm a little cornfused by what's going on. Generally, if I'm having a problem like this, I will figure out a way to force the result I'm looking for. e.g. in your code, I'd force that else to run... once I get it to run, break down what happened to make it run. Rudimentary, but it has served me well.
You use array of rules in
$this->form_validation->set_rules()
wrong.
If you want to pass the rules in array you must stick to the key names like described here http://codeigniter.com/user_guide/libraries/form_validation.html#validationrulesasarray
So instead of
$rules['input_name'] = "required"
try this:
array(
'field' => 'input_name',
'label' => 'Name that you output in error message',
'rules' => 'required'
)
