I was wondering if it was possible to do something like:
If "RadioButton1" is checked, then have it display the text in "Textbox2.text" with the Password characters.
Is this possible?
Use the UseSystemPasswordChar property:
Textbox2.UseSystemPasswordChar = (RadioButton1.Checked);
if (RadioButton1.Checked)
{
textBox2.PasswordChar = '*';
} else {
textBox2.PasswordChar = '*';
}
You can put this code on RadioButton CheckedChanged event...

I'm working on user consents. In my request I have these properties:
$newsLetters (bool|nullable),
$sms (bool|nullable),
$billEmail (bool|nullable),
I need update only one. So I need to find one which is not null and update it, if in my request is more than one properties with bool values i need to throw exception.
How can I achieve this?
My request extends spatie/laravel-data.
I don't understand why would you handle something like this on the backend (you can use radio button for this and always send only one value), you can use validation for requests or something like this:
$newsLetters = null;
$sms = true;
$billEmail = null;
$values = [$newsLetters, $sms, $billEmail];
$filter = sizeof(array_filter($values, function($el) { return $el === null;})) < 2;
if($filter) {
//return exception or whatever
} else {
//update values
}
I have made code with is work great for me, but I want to make email validation to require # on the field. Here is the code
if (!$('#contact_email').val()) {
if ($("#contact_email").parent().next(".validation").length == 0) // only add if not added
{
$("#contact_email").parent().after("<div class='validation' style='color:red;margin-bottom: 20px;'>Ange e-postadress</div>");
}
e.preventDefault(); // prevent form from POST to server
$('#contact_email').focus();
focusSet = true;
} else {
$("#contact_email").parent().next(".validation").remove(); // remove it
}
And the input is
<input type="text" class="form-control" placeholder="E-post" name="Email" id="contact_email" onblur="validate()">
I dont use basic email field because I don't want to be on english.
How can i implement # to be required on this text input. Thank you
Hey Use This function:
function validateEmail(email) {
var re = /^(([^<>()[\]\\.,;:\s#"]+(\.[^<>()[\]\\.,;:\s#"]+)*)|(".+"))#((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}])|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))$/;
return re.test(email);
}
found here:
Validate email address in JavaScript?
Try this for email validation:
function isEmail(email) {
var mailformat = /^\w+([\.-]?\w+)*#\w+([\.-]?\w+)*(\.\w{2,3})+$/;
if (email.match(mailformat)) {
return true;
} else {
return false;
}
}
Checking as follows:
if (email != "") {
if (!isEmail(email)) {
alert("invalid");
}
}
You can use regular expression to check for an "#" and a "." field.
Regex:
var regex= /\S+#\S+\.\S+/;
return regex.test(email);
The above code will return true if the regular expression is matched. This expression checks for an # and a . to be present in the given string.
Heres the documentation on .test http://www.w3schools.com/jsref/jsref_regexp_test.asp
I've noticed other answers have better regular expressions as the above will allow for multiple #'s and .'s to be present.
I am using Joomla 2.5 and I want to change the canonical link in the header.
I do this in category view (components/com_content/category/tmpl/default.php)
$url = JURI::root();
$sch = parse_url($url, PHP_URL_SCHEME);
$server = parse_url($url, PHP_URL_HOST);
$canonical = $this->escape($_SERVER['REQUEST_URI']);
$document->addCustomTag('<link rel="canonical" href="'.$sch.'://'.$server.$canonical.'"/>');
It prints the right canonical, but it also leaves the old canonical link there so that I have 2 canonical links in the header.
How can I change or delete the old canonical link?
I have found the following to work for me with Joomla! 3.2.1. You can directly modify the
$_links
variable in the JHtmlDocument object.
I'm doing a subset of the following in a particular view of my component because the URL that Joomla! is coming up with is not correct.
Hope this helps.
$document = JFactory::getDocument();
foreach($document->_links as $key=> $value)
{
if(is_array($value))
{
if(array_key_exists('relation', $value))
{
if($value['relation'] == 'canonical')
{
// we found the document link that contains the canonical url
// change it!
$canonicalUrl = 'http://www.something.com/index.php/component/my-component-name-here/?view=viewNameHere¶meterNameHere=parameterValueUsedInTheViewRightNow
$document->_links[$canonicalUrl] = $value;
unset($document->_links[$key]);
break;
}
}
}
}
What you probably want to do instead is something like the following:
$doc_data = $document->getHeadData();
$url = JURI::root();
$sch = parse_url($url, PHP_URL_SCHEME);
$server = parse_url($url, PHP_URL_HOST);
$canonical = $this->escape($_SERVER['REQUEST_URI']);
$newtag = '<link rel="canonical" href="'.$sch.'://'.$server.$canonical.'"/>'
$replaced = false;
foreach ($doc_data['custom'] as $key=>$c) {
if (strpos($c, 'rel="canonical"')!==FALSE) {
$doc_data['custom'][$key] = $newtag;
$replaced = true;
}
}
if (!$replaced) {
$doc_data['custom'][] = $newtag;
}
$document->setHeadData($doc_data);
This will grab all of the current head data from the document, including the canonical link that you want to replace. It will search through the custom set (where I'm guessing this will be) and if it finds it, replace it with yours. If it doesn't find it, then it tacks it on at the end. Just in case.
Potential problems with this that I can see right away:
If the tag contained rel='canonical' with single quotes it would not be found, so you may have to adjust that.
The tag may have been placed in a different section of what I've termed $doc_data. You may want to do a var_dump($doc_data}; to confirm the location of the variable in this array.
I'm using a model with DataType.EmailAddress. I would like to modify the address link in the run time, however it already has email link automatically that prevents my modification.
#{
var subject = "";
if (Model.Name.Length > 30)
{
subject = Model.Name.Substring(0, 30) + "...";
}
else
{
subject = Model.Name;
}
}
model => model.email
But I got
<a href="mailto:emailaddress">emailaddress</a>
instead of
emailaddress
Why the email address is converted into link form automatically? And how to stop it? I would like to keep the datatype to use validation though.
You're trying to print the value of the property: #model.Email.
DisplayFor is not what you want.
Also, you need to URL-encode the subject parameter, including the space after Re:.
I have a multidim array from my $_POST but I have to serialize() then save to the database...
Normally, I can serialize but I got some problem with slashes (apostrophe and double quote).
My array seems like this: $array["hu"]["category"]["food"] = "string";
But when the "string" contains "" or '' theres's shit...
I need some short code for add slashes, but thres a lots of wrong solutions out there.
p.s.: I'm a CodeIgniter user.
// update:
function addslashesextended(&$arr_r) {
if (is_array($arr_r)) {
foreach ($arr_r as &$val){
if( is_array($val) ){
addslashesextended($val);
}else{
$val = addslashes($val);
}
}
unset($val);
} else {
$arr_r = addslashes($arr_r);
}
}
Thx!
I think the best solution would be to use the codeigniter input class and active record class . Addslasches/escapes, and most general sanitization will be taken care of for you.
