Hi,

I would like to ask why I am getting the above error for this code:

PHP

if (isset($_GET['msg'])) { $mailbox_message = $_GET['msg']; } else { $mailbox_message = ""; }

then:

PHP

if (!strlen($mailbox_message)) { $mysql_query->bindParam(':param_message_mailbox', $mailbox_message = NULL, PDO::PARAM_NULL); }
else { $mysql_query->bindParam(':param_message_mailbox', $mailbox_message, PDO::PARAM_STR); }

Given all these questions, do you think a book on PHP would be a good investment?

Hi,

I have an input text control in my php page to allow user to enter thei profile address url which will be like this:

wwww.mydomain.com/PROFILE.ADDRESS

I want to know how can I let php validate it for me so only valid characters will be allowed such as alphabits, numbers, . (dot) and _ (underscore)?

Thanks,

Use a regular expression:

PHP

$ismatch = preg_match('/^[\w.]+$/', $input);
if ($ismatch) {
  echo "Valid";
}
else {
  echo "Invalid";
}

Hope this helps.

thanks but is it possible to have it validated while typping (while text changed) just like ASP.NET or only when form is posted?

Yes, you can do that using JavaScript, but after submitting the form, ALWAYS validate it from the server-side language (PHP in this case). The reason is that people could disable JavaScript in their browser, and then the text box wouldn't be validated anymore.
For the JavaScript, try this:

JavaScript

var inputField = document.getElementById('put-your-id-here');
inputField.onkeyup = function(e) {
    e = e || window.event;
    var re = /[^\w.]/;
    inputField.value = inputField.value.replace(re, '');
};

No, that won't work, meanwhile many non-ASCII characters are allowed in URLs.
I'd suggest to send a HEAD request to the URL (e.g. before submitting or when leaving the text field) and check the return code (200=OK, everything else: wrong).

placeholder even if focus

Jassim Rahma26-Oct-13 0:49

Jassim Rahma

26-Oct-13 0:49

Hi,

I am using an input text in my PHP project for email address and password. I made the place holder for both so it will be easy for users to know what is every textbox form. but when I load the page the email address textbox will be autofocus therefore it will lose the placeholder then user needs to take the focus just to know what's this textbox?

Is there anyway to keep the placeholder text even when the cursor is focused so it will only be disappeared when the user starts typing.

Thanks

Add this in HTML of chkPresent onclick=”AssignValueOnCheckboxTick(this.checked)"

Now Add this in Java Script

<script type="Javascript">

var cboMonth = document.getElementById('<%= cboMonth.ClientID %>');
var cboYear = document.getElementById('<%= cboYear.ClientID %>');

function AssignValueOnCheckboxTick(ischecked) {

if (ischecked)
{
var cboMonth.style.display = 'block';
cboYear.style.display = 'block';

}

else
{
cboMonth.style.display = 'none';
cboYear.style.display = 'none';
}

}

</script>

read bit value into checkbox in PHP

25-Oct-13 2:48

Hi,

I am having difficulties reading the bit value from MySQL and showing it in a checkbox in PHP.

The value is not showing and it's always unchecked!

This is what I am using:

PHP

$mysql_command = "CALL sp_get_member_personal_information(:param_member_guid)";

$mysql_query = $mysql_connection->prepare($mysql_command);
$mysql_query->bindParam(':param_member_guid', $_SESSION["member_guid"], PDO::PARAM_STR);

$mysql_query->execute();

$mysql_row_count = $mysql_query->rowCount();

if ($mysql_row_count <= 0) { exit(header("Location: home")); }

while ($mysql_row = $mysql_query->fetch())
{
    $is_private = (bool)$mysql_row["is_private"];
    $hide_contact_details = (bool)$mysql_row["hide_contact_details"];
}

and then:

PHP

<input type="checkbox" id="chkPrivateProfile" name="chkPrivateProfile" value="<?php echo $is_private; ?>"> My Profile is Private<br><br>
<input type="checkbox" id="chkHideContactDetails" name="chkHideContactDetails" value="<?php echo $hide_contact_details; ?>"> Hide my contact details<br><br>

I have no problem reading a varchar value but my problem is juts with the bit as it's my first time trying checkbox with php.

Please help...

Dynamic Data Scaffolding with static values

Hi,

I have a database field value, to which i am trying to assign some static values at the metadata level. I want to see this as a dropdown list, with predfined static values. I heard you can achieve this dropdown by defining a foreign key relationship.
is there a way to do this without the table?

==

[DisplayNameAttribute("App Form")]
    [UIHint("AppType")]
    [Required]
    public OptionType AppType { get; set; }</pre>
===

<pre>public enum OptionType
   {
       CheckBox=1,
       radiobutton=2,
       freeform=3,
       dropdown=4

Dynamic questionnaire

Hi,

I am building a dynamic questionnaire for our team.

With that said, all information is stored in database, like question text and its answers. Using LINQ to select out information and display on web page using asp.net aspx page.

We also stored the mandatory field in the database. On form submit, I am trying to check if all the mandatory questions were answered.

I am little stumped here - should I create the requiredfieldvalidators dynamically and check this manner? Should I add these validators on button_click or page_load? any other way to check for validation? I guess the challenge for me arises with the fact, i have check this in code behind page.

Thanks a lot!
