For help clarifying this question so that it can be reopened, visit the help center. Closed 6 years ago . I HAVE searched on here but, despite finding LOTS of similar and most likely MUCH more complicated situations, couldn't find an answer to what I am wanting to do. Basically, on my site's search form I want to

问题 In a LibreOffice Writer document, how do I make a radio button group? I cannot get my buttons to "group". I'm using LibreOffice 5.3.4.2 (x64). I place multiple Radio buttons controls in my Writer document. I select two buttons and, in the controls' Properties, I assign them the same Group Name. I select two other buttons and assign them their own, same Group Name. Example : "Do you like dogs? O Yes, O No." (These would be the " Dogs " group) "Do you hate cats? O Yes, O No." (These would be

问题 PHP keeps saying unidentified index: gender ? I'm not sure where the error is. HTML: <label>Gender:</label> <input type="radio" name="gender" value="1">Male <input type="radio" name="gender" value="0">Female JQuery: gender: $("input[@name=gender]:checked").val() PHP: $gender = $_POST['gender']; if($gender == '') { echo 'Please select gender'; } 回答1: $("input[@name=gender]:checked") That is an invalid selector in modern jQuery. This means that no element is found, and therefore no value is set
