PHP - Mvc / Header("content-type: Image/jpeg");

Do I need to check both the "Image Size" AND "Image Dimensions" for files that Users upload to my website?

Currently I have...

// ********************
// Check File-Size. *
// ********************
if (empty($errors)){
// Check File-Size in Bytes.
if (filesize($tempFile)<4000){
// File too small.
$errors['upload'] = 'File-size must be greater than 4 Kilobytes.';
}elseif (filesize($tempFile)>100000){
// File too big.
$errors['upload'] = 'File-size must be less than 100 Kilobytes.';
}else{
// File-Size Okay.
// Continue Processing Upload...
}
}//End of CHECK FILE-SIZE



I guess I haven't been worrying about "File Dimensions" because I resize everything here...

// **********************
// Set New Dimensions. *
// **********************

// Capture Dimensions on Original Image.
$origWidth = imageSX($origImage);
$origHeight = imageSY($origImage);

if ($origWidth > $origHeight){
$newWidth = 100;
$multiplier = $newWidth/$origWidth;
$newHeight = $origHeight * $multiplier;
}

if ($origWidth < $origHeight){
$newHeight = 100;
$multiplier = $newHeight/$origHeight;
$newWidth = $origWidth * $multiplier;
}

if ($origWidth == $origHeight){
$newWidth = 100;
$newHeight = 100;
}

Hi,

I want to separate out the file name from an image url. Not sure the best way to do it? I want to basically select all text after the last / slash. eg - image.jpg would be the result from http://www.google.com/images/image.jpg

What's the best way to do it?

Cheers

Rob

Hi..

I used this code for displaying formatted number and I notice that instead comma(,) it become point(.):

Code: [Select]
$P28_maxdoz = $row['P28_maxdoz']; 
$P28_maxdoz = number_format($P28_maxdoz, 2, '.', ',');


<table>
<tr>
<td><input type='text' name='P28_maxdoz' value="<?php echo $P28_maxdoz;?>"></td>
</tr>
</table>

the output is : 22.782.20

i need output is : 22,782.20

Thank you

Hi guys

I am a newbie with PHP and I have been trying to solve this problem for 3 days..

Ive set up a booking form on my website to be sent directly to my email once the client clicked on the send button..
The problem I am having while checking these pages on wamp is that the booking form is ok but when I click on the send button the following message error appears
"Warning: mail() [function.mail]: Failed to connect to mailserver at "localhost" port 25, verify your "SMTP" and "smtp_port" setting in php.ini or use ini_set() in C:\wamp\www\fluffy_paws\booking_form2.php on line 27"

When I check online I have this message "500 - Internal server error.
There is a problem with the resource you are looking for, and it cannot be displayed."

Are my codes wrong???

My webhosting is Blacknight.com , Im on Windows Vista, my internet is a dongle with O2 ireland

Thanks for your help!

Hi Guys,

I need help I have setup a code recently :

this is the code :
$za['MIN(spec_positionid)']

and it gave me an error saying : Cannot use object of type stdClass as array

but if I change to this :

$za->spec_positionid

it works, but I need to get the MIN value from the database.

can someone please help.

this is very urgent for me.....

I have a table with a list of users and an edit button and delete button.  When the edit button is pressed on a site it passes the user_id as p_id to the page that catches it and displays the data.  The problem is when I click on the "update user" button, I get the following error:

Warning: Undefined variable $the_user_id in C:\xampp\htdocs\3-19-21(2) - SafetySite\admin\edit_user.php on line 10

Fatal error: Uncaught TypeError: mysqli_fetch_assoc(): Argument #1 ($result) must be of type mysqli_result, bool given in C:\xampp\htdocs\3-19-21(2) - SafetySite\admin\edit_user.php:14 Stack trace: #0 C:\xampp\htdocs\3-19-21(2) - SafetySite\admin\edit_user.php(14): mysqli_fetch_assoc(false) #1 {main} thrown in C:\xampp\htdocs\3-19-21(2) - SafetySite\admin\edit_user.php on line 14

The weird thing is I had another update user page with a table I created that ran the query to update the table in the database just fine.  But as I created it, it didn't look all that great so I recreated the page and used a bootstrap table because of the much cleaner look.  Both pages have the exact same PHP code, the only difference is the bootstrap table I added in.  So I'm really at a loss with this.  Other than the table and PHP code, there is a script at the bottom of the page for the table itself to allow for searching within the table, i'll include that as well.  The PHP code is as follows:

<?php

//THE "p_id" IS BROUGHT OVER FROM THE EDIT BUTTON ON VIEW_ALL_USERS

if (isset($_GET['p_id'])) {

    $the_user_id = $_GET['p_id'];

}

// QUERY TO PULL THE SITE INFORMATION FROM THE p_id THAT WAS PULLED OVER

$query = "SELECT * FROM users WHERE user_id = $the_user_id ";

$select_user = mysqli_query($connection,$query);

//SET VALUES FROM ARRAY TO VARIABLES

while($row = mysqli_fetch_assoc($select_user)) {

    $user_id = $row['user_id'];

    $user_firstname = $row['user_firstname'];

    $user_lastname = $row['user_lastname'];

    $username = $row['username'];

    $user_email = $row['user_email'];

    $user_phone = $row['user_phone'];

    //$user_image = $row['user_image'];

    $user_title_id = $row['user_title_id'];

    $user_role_id = $row['user_role_id'];

   }

THE UPDATE QUERY CODE....................................................................................................................

<?php

if(isset($_POST['update_user'])) {

    //$user_image = $_POST['user_image'];

    $user_title_id = $_POST['user_title_id'];

    $query = "UPDATE users SET ";

    $query .= "user_id = '{$user_id}', ";

    $query .= "user_firstname = '{$user_firstname}', ";

Hi guys

I'm struggling a bit, I need to replace a word that occurs multiple times in text with an array("up","down","forward","backwards") of words.


$find = "left";
$replace = array("up","down","forward","backwards");
$text = "left left left left";

echo str_replace($find,$replace,$text);


The Output is: array array array array

Did try this with a foreach statement as well, but no luck. Is there a better way of doing this? 

Thanks

Cannot modify header information - headers already sent by (output started at )  on line 179
 I labeled 179 its at the bottom.
I understand this means its already generating the html but not how or where.  A solution would of course be nice but if some one could tell me even how to figure it out it would be great.

I am come across a very odd situation when I include a connnet.php file.  For some reason it messes up the layout of the page.  However when I enter the connect code onto the page it looks fine.

Code: [Select]
include("connect.php");
What is also strange is that when I include the header and footer it works fine.  For some reason it is just when I include the connect.php file.

Is this because it is above the CSS file?

Code: [Select]
include("header.php");
Code: [Select]
include("footer.php");

I am getting the following error when using composer: "continue" targeting switch is equivalent to "break". Did you mean to use "continue 2"?

Just started.  I am pretty sure composer.json wasn't changed.  journalctl doesn't show anything.  Maybe Doctrine related, however, nothing seems to help.

Any ideas?

Dear php freaks,
I was asked to create an adult content filter system as my final project and am actually thinking of using php. So i would like to know how possible this is.
Any useful suggestions are welcome as i am a bit new in php.
Thank you.

I've found a nice "content slider", and would now need a little help to get the info from MySQL, and show that in the "slider".

The slider generates the following example:
Code: [Select]
<div id="featured" >
<ul class="ui-tabs-nav">
    <li class="ui-tabs-nav-item ui-tabs-selected" id="nav-fragment-1"><a href="#fragment-1"><img src="images/image1-small.jpg" alt="" /><span>15+ Excellent High Speed Photographs</span></a></li>
    <li class="ui-tabs-nav-item" id="nav-fragment-2"><a href="#fragment-2"><img src="images/image2-small.jpg" alt="" /><span>20 Beautiful Long Exposure Photographs</span></a></li>
    <li class="ui-tabs-nav-item" id="nav-fragment-3"><a href="#fragment-3"><img src="images/image3-small.jpg" alt="" /><span>35 Amazing Logo Designs</span></a></li>
    <li class="ui-tabs-nav-item" id="nav-fragment-4"><a href="#fragment-4"><img src="images/image4-small.jpg" alt="" /><span>Create a Vintage Photograph in Photoshop</span></a></li>
</ul>
<!-- First Content -->
<div id="fragment-1" class="ui-tabs-panel" style="">
<img src="images/image1.jpg" alt="" />
<div class="info" >
<h2><a href="#">15+ Excellent High Speed Photographs</a></h2>
<p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nulla tincidunt condimentum lacus. Pellentesque ut diam....<a href="#" >read more</a></p>
</div>
</div>
<!-- Second Content -->
<div id="fragment-2" class="ui-tabs-panel ui-tabs-hide" style="">
<img src="images/image2.jpg" alt="" />
<div class="info" >
<h2><a href="#" >20 Beautiful Long Exposure Photographs</a></h2>
<p>Vestibulum leo quam, accumsan nec porttitor a, euismod ac tortor. Sed ipsum lorem, sagittis non egestas id, suscipit....<a href="#" >read more</a></p>
</div>
</div>
    <!-- Third Content -->
....
</div>
First I have to get all the headers/titles to the list/tab (menu):
Code: [Select]
<ul class="ui-tabs-nav">
    <li class="ui-tabs-nav-item ui-tabs-selected" id="nav-fragment-1"><a href="#fragment-1"><img src="images/image1-small.jpg" alt="" /><span>15+ Excellent High Speed Photographs</span></a></li>
    <li class="ui-tabs-nav-item" id="nav-fragment-2"><a href="#fragment-2"><img src="images/image2-small.jpg" alt="" /><span>20 Beautiful Long Exposure Photographs</span></a></li>
    <li class="ui-tabs-nav-item" id="nav-fragment-3"><a href="#fragment-3"><img src="images/image3-small.jpg" alt="" /><span>35 Amazing Logo Designs</span></a></li>
    <li class="ui-tabs-nav-item" id="nav-fragment-4"><a href="#fragment-4"><img src="images/image4-small.jpg" alt="" /><span>Create a Vintage Photograph in Photoshop</span></a></li>
</ul>
.. then the "title" is needed (again), and image, text for the fragments/divs.
Code: [Select]
<div id="fragment-?" class="ui-tabs-panel ui-tabs-hide" style="">
<img src="images/image2.jpg" alt="" />
<div class="info" >
<h2><a href="#" >20 Beautiful Long Exposure Photographs</a></h2>
<p>Vestibulum leo quam, accumsan nec porttitor a, euismod ac tortor. Sed ipsum lorem, sagittis non egestas id, suscipit....<a href="#" >read more</a></p>
</div>
</div>Do not really know how to resolve this in a good way.
