PHP - Display Text If Picture Not Present

I'm doing an ajax call from javascript using jquery library:

Code: [Select]

    ajaxCall: function(process, obj, type){     
        $.post("registration-post.php", type + "=" + process,
            function(data){
                if(data==""){
                    $(obj).css(registration.errorNotificationType, registration.validatedColour);
                }else{
                    $('.error').append($.trim(data) + "<br />");
                    $(obj).css(registration.errorNotificationType, registration.errorColour);
                    registration.progress = false;   
                }
            }
        );
    }


When the ajax calls the php page, I want the php page to know what post information the javascript has sent, rather than pre-defining what the PHP should be trying to retrive from the POST data.

Something like


          // pseudo

          $_POST["whateverwassentfromajax"]



I want to do this because I want to have one function doing everything. So in my javascript I am saying, check if the username and email have already been used...
But i dont want to call two different php functions.



//pseudo

function 1(){
      $_POST["username"];
}
function 2(){
      $_POST["email"];
}



Is there a special way to know which post data has been sent.
Or do i need to do a few if statements in php.

Hi, guys.

I want to present different ads to visitors in different countries.  For example, if a visitor is in Australia, I want him/her to see a different ad from, say, a visitor from the UK. Can this kind of thing be done with PHP? If so, will installing such a code slow down my site?

Any help will be appreciated very much.

Hi,

 

I have made a database linked with php that I use a html form for.

The HTML form requests a particular date to retrieve, and the php form it is linked to then retrieves data from the MySQL database from that date.

 

My question is: I want there to be a restriction so that the retrieval can only be for dates before the present date (and certainly not any date in the future).

 

e.g. if it is 6th July 2020, then the database can only retrieve from the 5th July 2020 and before. (7th July 2020 onwards also is not allowed.)

Is there a way I can do it? Anyone who can guide me to a particular code function or something of that sort - I would be deeply grateful as my searches have not come up fruitful.

Hello All,
 
I have been wrestling with a regex for a couple of hours now and I finally had to give in and ask for help.  The weird thing is that it works if there are no new lines in the text, it fails if there is a new line(s) present.  
 
The code:

$matches = array();
$pattern = '~\[CUSTOM_TAG(.*?)\](.*?)\[/CUSTOM_TAG\]~';
preg_match_all($pattern, $html, $matches);
if (!empty($matches[0])){
foreach($matches[0] as $code){
$parameter = preg_replace($pattern, '$1', $code);
$content = preg_replace($pattern, '$2', $code);//get the content between the pattern
}//foreach($matches[0] as $code){
}else{
echo 'Match failed';
}//if (!empty($matches[0])){

 
So with that code in mind, if the $html variable (the text to be processed) is:

$html = '<h1>Hello, world!</h1><p style="color:#ff0000;">Some red text</p>';

A match is found.  
 
 
If the $html variable is:

$html = '<h1>Hello, world!</h1>
<p style="color:#ff0000;">Some red text</p>';

Match not found
 
Hopefully I'm just missing something simple in my regex.
 
Thanks in advance!

in my code below the **data is extracted correctly for the first foreach but doesn't return anything for 2nd foreach though selected one present inside the 2nd foreach** i still get the error Warning: Invalid argument supplied for foreach() for line `foreach ($authorlist as $post)`... however the 2nd foreach returns data correctly as soon as i remove the first foreach loop. 

Hello, I have started a DB for simple web based inventory system, I have only dabbled in PHP before 6 weeks ago, within the last 6 weeks with some help and going through countless tutorials and asking questions when I need. At this time setup an insert, delete and update function for this db and are working perfectly, now what I need to know is there a way to display something like 'in stock' and 'out of stock' using php, based on the value of the quantity in my db next to the item in a table? Example : when the table is generated it will display: | Part number | Description | Stock              |  (normally Stock would show the quantity of each part, I just wish to |10-1111         | Some info   | In Stock          |    display In or out os stock) |10-1112         | Some Info   | Out of Stock   |   I the only code I have is the tables and just not sure what to do next to get the results I have described above. So I will include the table code I have and see where we can go from there. Or if you have some webs site that I can read through that will be great as well as long as it can give me basic instruction on how to do this. Reminder, I am self taught and still learning.

<?php
         $con = mysqli_connect("localhost","user","pass","part_inventory");
	// Check connection
if (mysqli_connect_errno()) {
  printf("Connect failed: %s\n", mysqli_connect_error());
	exit();
} else {
	$result = mysqli_query($con, "SELECT * FROM amp20");
	
	echo "<table border='1'>
	<tr>
	<th>ID</th>
	<th>Part number</th>
	<th>description</th>
	<th>location</th>
	<th>Quantity</th>
	</tr>";
	
		while ($row = mysqli_fetch_array($result)) {
			echo "<tr>";
			echo "<td>" . $row['amp20ptid'] . "</td>";
			echo "<td>" . $row['partnum'] . "</td>";
			echo "<td>" . $row['description'] . "</td>";
			echo "<td>" . $row['location'] . "</td>";
			echo "<td>" . $row['quantity'] . "</td>";
			echo "</tr>";
		}
			echo "</table>";
			
	mysqli_close($con);
}

I have a field in my database called description. How can I echo out only 500 out of the 2000 max characters?

Like for example:

Code: [Select]
$query = mysql_query("SELECT description FROM `servers` ORDER BY votes DESC LIMIT 5");

If I were to echo out the value of description for the database, how can I only echo out the first 500 characters?

Sorry if this is too obvious or hard to understand.

I'm echoing a database value onto a webpage, the value in question is a large paragraph of text. I need it to only display the first 40 characters or so of that text, then trail off with a "..."

So the users will be able to click a 'More Info' button which will take them to a page containing the full paragraph of text.

I'm just not sure how to cut off the text after 40 characters.

Any help HUGELY appreciated

Hi there,

I am trying to write a simple piece of code that will display a little text phrase on every Friday 13th in any year.

How would I best go about doing this?

Thank you.

Hi,

Wonder if someone could help with the problem below. Got a main page that includes a header, footer and a link to a database. I can get the two Includes to work but can't seem to display the database fields in the body of the page. What has me baffled is that it appears to be connecting to the database, (Opening the connection to the database server The connection worked. The link is: Resource id #3) but no text (see below for database text) is appearing on the screen. Yet I'm not getting a "page_not_found" message. I can go to the database in MYSQL console and query it successfully. Read and (hopefully) applied the section Debugging: A Beginner's Guide, but still can't see the problem. Any help greatly appreciated.

hey guys so im trying to display data into text boxes that are fetched from database according to checkbox with value id.

processing is located before <!DOCTYPE html>:

if(isset($_POST['edit_event']) && isset($_POST['check']))
{
    require "connection.php";
    foreach ($_POST['check'] as $edit_id) 
    {
	$edit_id = intval($GET['event_id']); //i tried (int)$edit_id;
	$sqls = "SELECT event_name,start_date,start_time,end_date,end_time,event_venue FROM event WHERE event_id IN $edit_id ";
	$sqlsr = mysqli_query($con, $sqls);
	$z = mysqli_fetch_array($sqlsr);
     {
}

button and form opens:

<form method="post" action="event.php">
<input type="submit" name="edit_event" value="Edit Event">

this is the html where the data will be echoed:

<div id="doverlay" class="doverlay"></div>
<div id="ddialog" class="ddialog">
    <table class="cevent">
    <thead><tr><th>Update Event</th></tr></thead>
    <tbody>
        <tr>
            <td>
            <input type="text" name="en_" value="<?php echo $z['event_name']; ?>">
            </td>
        </tr>
        <tr>
            <td>
            <input type="text" name="dates_" value="<?php echo $z['start_date']; ?>">
            <input type="text" name="times_"  value="<?php echo $z['start_time']; ?>">
            </td>
        </tr>
        <tr>
            <td><input type="text" name="datee_" value="<?php echo $z['end_date']; ?>">
            <input type="text"  name="time_" value="<?php echo $z['end_time']; ?>">
            </td>
        </tr>
        <tr>
            <td><input type="text" name="ev_" value="<?php echo $z['event_venue']; ?>">
            </td>
        </tr>
        <tr>
            <td><input type="submit" name="update" value="Update Event" id="update">
            <input type="submit" id="cancelupdate" name="cancel" value="Cancel" >
            </td>
        </tr>
    </tbody>
    </table>
</div>

this is the part which is populated by data from database where isset($_POST['check']) gets the 'check' from:

echo 
    "<tr>
        <td><input type='checkbox' name='check[]' value='$id'>$name
      </td>
     </tr>";

</form> thanks in advance!

I wonder if someone can advise me on how to best tackle this issue.

At the moment I am displaying a gallery of images pulled from the database. These are displayed as a thumbnail across my page, currently 4 in each row (then a new row is started dispalying the next 4 thumbnails). This works fine and does exactly what it should do.

Now however I would like to display the username of who uploaded the image underneath each thumbnail.
So it would go something like this:

Display first 4 thumbnails pulled from database - breakline - Display username under each thumbnail - repeat for remainder of images, e.g:

image    image   image   image
user       user      user     user

image    image   image   image
user       user      user     user

How would I go about this so it doesn't just display all the images in one vertical column, e.g:

Image
User
Image
User
Image
User

I hope this makes sense.

Any help would be greatly appreciated.
