问题 I would like to use select2 to show a company search. If the company the user is looking for is not in the current dataset we need to show a company request form to add the data. html <head> <link href="https://cdn.jsdelivr.net/npm/select2@4.1.0-beta.1/dist/css/select2.min.css" rel="stylesheet" /> <script src="https://cdn.jsdelivr.net/npm/select2@4.1.0-beta.1/dist/js/select2.min.js"></script> </head> <body> <select class="js-example-basic-single" name="company"> <option value="1">(FB)

How do you read the value of a maxLength validator so that you can print it into the form?

由 元气小坏坏 提交于 2020-12-13 03:35:51
问题 I have a reactive form which uses a validator to control the length of the input. I would like to read that length back again in the template so that I can guide the user as to what the maximum length actually is but I can't figure out how to read it from the form. Is that possible? // investor-signup.component.ts export class InvestorSignupComponent implements OnInit { public investorForm = this.fb.group({ name: ['', [Validators.required, Validators.maxLength(5)]], // I want to access be

PHP form key bug

问题 Can someone look at my two functions below and suggest what I can do? I have created two functions that basically creates a unique key and this is echoed in a hidden field in a form and then straight after I check if the form has been submitted the second function checks to see if the key in the hidden field matches the key in the session. The problem I am having is now and again it just redirects me to to the forbidden page suggesting the keys don't match although I have not edited the form

问题 Been trying for hours and hours to get my multi entity form to work, but it really breaks my head and none of the examples I've found work. I checked the Collection form type documentation and form collections, as well as the Entity form type. I have a User entity, UserRole entity and a Role entity.
