i have been trying in create check on form validation on laravel
i need to query input with date and check more than check with many messages
like
if(){
$this->errorSchema->addError($error, $name); //symfony 1 way
}
how and where should i do that i have been thinking in creating custom validtaion but it returns true or false i need the date in the query to display like "this place is used for user XXX" XXX is data i got in the query
i want to return multi error if some record exist like
$resultset = 'select person form events where date < "some date"';
if ($resultset[enddate] > 'somedate'){
my error message should be "you cant add this event as $resultset['person'] overlape in this date "
}elseif($resultset[startdate] > 'somedate'){
i need here to return deffrent error message like "start date is overlapping with resultset['person']"
}
i am using requests class in laravel so please recommend me a method to override or any other way to this in laravel
thanks in advance
You can try to SELECT data which you'd like to return, your "XXX", from table by user's input.
Simple SELECT *** FROM table WHERE smth = user's_input;
If it return smth, you can just add it to your validator such as: "this place is used for user".$smth;
Else (if nothing returned, you send to user your default answer.)
Also if you add more code it will be easier to help you :)

I used this query to update the status column.
$val="1";
vehicles::where('id' , '=' , $veh_status)->update(['status' => $val]);
But when I submitted the status value doesn't change.
you can trace your query by using ->toSql() method !
try this to find whats happening in back
Not sure what the problem is there because you haven't given much info to work with, but you can check these suggestions:
Check if the column is set to be mass assignable in the model class, that is, it is in the fillable[] array.
make sure the id you pass to the where() function is valid.
Try using another function, save() which will achieve the same results you seek, like this;
// filter the vehicle
$vehicle = vehicles::where('id', '=', $veh_id)->first();
or
$vehicle = vehicles::find($veh_id);
$vehicle->status = 1;
$vehicle->save();
Lastly, I noticed your id variable you pass to the where the () function is called $veh_status "presumably - vehicle status" and not $veh_id, "presumably - vehicle id" so probably check that out.

I created form for customers, I need to do validate customer name like
1 - type the new name into item P1_CUST_NAME.
2 - after leaving this item go to database and check if this name already exist or not.
3 - display alert or message for the client.
4 - prevent the client from navigating a way from this item until he enter valid data.
Yes, you can create server side validation by using Dynamic Action and JavaScript function apex.server.process.
A basic example to demonstrate-
Create a page item e.g. P4_NAME in your page
Create a page process and select the execution point as "AJAX
CALLBACK".
In below code I am checking the P4_ITEM value, you can write your own logic to validate.
BEGIN
IF :P4_NAME = 'HIMANSHU'
THEN
HTP.prn ('SUCCESS');
ELSE
HTP.prn ('ERROR');
END IF;
END;
Now create a new dynamic action and select the Event as "LOSE FOCUS", Selection Type as "Item(s)" and in Item(s) select the item name.
Create a true action and select "execute JavaScript Code".
In code section, implement apex.server.process like below-
apex.server.process('validate_name',
{
pageItems : '#P4_NAME'
}
,
{
dataType : 'text', success : function(data)
{
if(data != 'SUCCESS')alert(data);
}
}
)
The first argument is the page process name(validate_name) which we have create earlier, second the data you want to submit to the process and third is options.
For more details on apex.server.process
It is done. Refresh your page and check. On validation failure you will get an alert.
You can customize your JS code further to display error messages in more fancy way instead of showing alert.
I have a login system for my webapp that works well using the Zend auth adapter but the problem is I want the email to be case insensitive when a user logs in. I am using Oracle as the back end DB and normally I would user the LOWER(EMAIL)=LOWER(:email) method. I tried to pass that Oracle function in the setIdentityColumn() but I get the error:
The supplied parameters to Zend_Auth_Adapter_DbTable failed to produce
a valid sql statement, please check table and column names for
validity.
protected function _getAuthAdapter()
{
//$dbAdapter = Zend_Db_Table::getDefaultAdapter();
$db = Zend_Registry::get('db');
$authAdapter = new Zend_Auth_Adapter_DbTable($db);
$authAdapter->setTableName('USER_TABLE')
->setIdentityColumn('LOWER(EMAIL)') //Tried to pass LOWER()
->setCredentialColumn('ENCODED_PW')
->setCredentialColumn('PASSWORD');
return $authAdapter;
}
The error is coming from the function _authenticateCreateSelect() in the Zend_Auth_Adapter_DbTable class. The problem is this part of the script:
$dbSelect->from($this->_tableName, array('*', $credentialExpression))
->where($this->_zendDb->quoteIdentifier($this->_identityColumn, true) . ' = ?', $this->_identity);
The quoteIdentifier() method is like PHP quote() and is turning a query like this:
select * from LOWER(:email)
into this:
select * from "LOWER(:email)"
Anyone see a way around this?
Kind Regards
Nathan
Try something like this:
$authAdapter->setTableName('USER_TABLE')
->setIdentityColumn(new Zend_Db_Expr('LOWER(USERID)'))
->setCredentialColumn('PASSWORD');
The problem is that if you pass 'LOWER(USERID)' as a simple string, Zend will put quotes around it, causing it to create an invalid query. Using Zend_Db_Expr will stop Zend doing this.
(reworded the question hours later to be more descriptive)
I need a little advice on understanding Propel setters/validators in a standalone (non-framework) development.
The documentation on validation states:
Validators help you to validate an input before persisting it to the database.
... and in validator messages we can provided coherent advice on where users can correct entries that don't pass Propel validation.
The sample usage of a validator reads:
$user = new User();
$user->setUsername("foo"); // only 3 in length, which is too short...
if ($objUser->validate()) {
...
The problem I have found with this is 'what if you cannot setXXX() in order to validate it?'
I have a column type DATE and I invite a visitor to enter a date in a web form. They mistype the date and submit 03/18/20q2
I would hope that one of my custom validators would be able to report a validator message and return the form once more to the user to be amended, however this occurs first:
Fatal error: Uncaught exception 'PropelException' with message 'Error parsing date/time value: '03/18/20q2' [wrapped: DateTime::__construct() [<a href='datetime.--construct'>datetime.--construct</a>]: Failed to parse time string (03/18/aaa) at position 5 (/):
In my tests I couldn't get any simple or CustomValidator to fire once I'd written (for example):
$event= new Event();
$event->setDateStart($form_value_for_date); // where values is "03/18/20q2"
I understand why this is so - it would not make sense to be able to create and try to manipulate a new object if you cannot rely on its fields, even before you save it.
The dilemma this gives me is:
If a fatal error can result from invalid entry preventing Propel validation from handling it for me (and therefore the user) and sending back a useful message, should I bother with Propel validation as well as my own security/courtesy validation ?
I cannot find any mention in the docs of what happens if you give Propel - for whatever reason - a value it doesn't anticipate for the field, or how to handle it.
I do hope this makes sense and that someone can point me at a method that will mean I only need to validate input in one place.
I've hacked together a rough ready solution that will allow me to:
Pre-validate a field against a CustomValidator without setting it in the new object
Retrieve the validator's message for return to the user
I take the form input, sanitise it of course, and then create an object:
$event = new Event();
With my user form in mind, I then pre-check the field I know will fatally fall over if the content's bad, and only set the field in my new object if it would validate:
if ($check = $event->flightCheckFail('StartingDate','DateValidator',$sanitisedFormVal))
echo $check;
else
$event->setStartingDate($sanitisedFormVal);
Method flightCheckFail() will return false if the data from the form would validate against the field, it returns the validator's error message if it would fail.
The method's added to my Event class as follows. Its arguments are the field name, the class of the CustomValidator (which simply runs an strtotime check), and the sanitised form value:
public function flightCheckFail($name,$validatorClass,$value) {
$colname = $this->getPeer()->getTableMap()->getColumnByPhpName($name)->getName();
$validators = $this->getPeer()->getTableMap()->getColumn($colname)->getValidators();
foreach($validators as $validatorMap)
if ($validatorMap->getClass() == $validatorClass) {
$validator = BasePeer::getValidator($validatorMap->getClass());
if ( $validator->isValid($validatorMap, $value) === false)
$failureMessage = $validatorMap->getMessage();
} // if $validatorMap->getClass() == $validatorClass
if($failureMessage)
return $failureMessage;
else
return false;
}
I should be able to use this to work around handling dates in forms, but I'll need to check what other types in Propel might require this sort of handling.
I can stop the form handling wherever this reports a validator error message and send it back. When the user enters valid data, Propel (and normal Propel Validation) gets to continue as normal.
If anyone can improve on this I'd love to see your results.
You could also use a MatchValidator, with a date RegExp, no need for extra functions
I have the following code in zend:
$arrErrors=array();
if (!empty($this->post['submit']))
{
// Each time theres an error, add an error message to the error array
// using the field name as the key.
if (empty($this->post['client_name']))
$arrErrors['client_name'] = "Please Enter Client's name as it appears in the carrier software";
}
if i set $this->view->arrErrors=$arrErrors in the controller,
Can I access it as $this->arrErrors['client_name'] in the view?
i aplogize for a silly question.
Here is right approach:
$this->view->arrErrors=arrErrors['client_name'];
Use the above code in the controller
