Hi,

I am using MDBootstrap Angular v6. I have an issue regarding form validation. I just want know what is the way to apply more than one validation rules over one input field. In your documentation, there you have not written about this. Please review the following code.

template.html :

<form [formGroup]="candidateDetailsForm">

      <div class="md-form form-container">

          <input mdbInputDirective type="text" id="name" name="name" class="form-control"

          formControlName="name" [errorMessage]="'Name is required.'" [validateSuccess]="false"

          >

          <label for="form1" class="">Enter Your Name</label>

      </div>
</form>

component.ts :

{
     this.email = new FormControl('', [ Validators.required, Validator.email ]);
}

Thank you and I look forward to your kind response.

Regards,

Shibnath Salui

Dear Shibnath Salui,

Please check my code. The checkError() method checks which error got name input, and returns proper error message to the [errorMessage] input.

HTML:
<div>
<pre><form [FormGroup]="candidateDetailsForm">

<label for="form1"class="">Enter Your Name</label>

</div>

</form></pre>
</div>
TS:
<div>
<pre>import { Component } from '@angular/core';

import { FormGroup, Validators, FormControl } from '@angular/forms';

@Component({

selector:'app-root',

templateUrl:'./app.component.html',

styleUrls: ['./app.component.scss']

})

export class AppComponent {

candidateDetailsForm:FormGroup;

name:FormControl;

constructor() {

this.name=newFormControl('', Validators.compose([Validators.required, Validators.email]));

}

checkError() {

if (this.name.getError('email')) {

return'Email is not valid';

} else if (this.name.getError('required')) {

return'Input is required';

}

}</pre>
</div>
Best Regards,
