PHP - Get Parameter From Url

Hi all   Is it possible to have a function with two parameters but and then check if one is passed before using it.   In this code here I want to remove spaces and change to lowercase.   If the $extra parameter is set I want to add that to the end of the string.    

function className($nametoUse, $extra){

I am trying to create a simple voting form. Everything goes well until I submit and then I get a Warning: mysqli_error() expects exactly 1 parameter, 0 given on line 79 error. I am assuming it is not pulling the ID correctly but as I am new to php and mysqli I cannot exactly say if it the way the code is written or if I am calling the parameter incorrectly in the query. Again I am new to to this so please be gentle. Below is my code. It pulls the drop down list correctly and echo's correctly but I believe my post query to be a little out of wack. Could someone point me in the correct direction? It would be very appreciated.

<form action="businesstype_update.php" method="post">
<?php 
if(isset($_POST['voteall'])){
	
	$vote_lg = "update membertest where id={$row_lg['id']} set vote=vote+1";
	
	$run_lg = mysqli_query($con, $vote_lg) or die(mysqli_error());
	
}

$result_lg = mysqli_query($con, "SELECT id, business FROM membertest WHERE businesstype='large'");

echo "Vote for large business of the year! <SELECT name='business'>\n";
echo "<option>Select a large business</option>";
while($row_lg = $result_lg->fetch_assoc()) {
echo "<option value='{$row_lg['id']}'>{$row_lg['business']}</option>\n";	
}
echo "</select></br></br>\n";
echo "<input type='submit' name='voteall' value='voteall'>";

$result_lg->close();

$con->close();

I have a pagination class that uses PHP_SELF to display the proper URLs when generating the pagination buttons.  I need PHP_SELF to be a class parameter so that if the page is not defined in the parameter, then use PHP_SELF.  The reason for this is because I generate the class in an ajax file and it is returning the URL of the ajax file, not of the page I am running the ajax on. I just don't know how to add the parameter to the class.

The class is below:

Code: [Select]
<?php

Hello

I am experiencing some issues with a function and I cannot identify the problem.
The function is not receiving any parameter.

The URL values are passed correctly.  I used echo to display the parameters outside the function and that worked.
I also used echo to display the parameters inside the function and no parameter were displayed. 
So the function is not receiving parameters. 


Code: [Select]
<?php

$find = $_REQUEST['u_find'];
$field = $_REQUEST['u_field'];
$searching = $_REQUEST['u_search'];


 echo"(1a)$find, (1b)$field, (1c)$searching";//outside function

function test_display($searching, $field, $find)
{
   echo"(2a)$find, (2b)$field, (2c)$searching";//inside function
 
}

?>

Hey guys,

I'm dealing a url that is similar to hxxp://domain/directory/?#{$id}.

What I'm trying to do is extract $id from that.   Its not available as a $_GET variable and $_SERVER['REQUEST_URI'] comes up as "/directory/?".

Does anyone know how I could retrieve $id ?

Thanks

Hi all

I have a form that i need to submit a get to the URL and then a second form that sends a different URL parameter but keeps the first in place?

Here's my code:

Code: [Select]
<select name="category" onChange="this.form.submit();">
            <option value= >--Choose category--</option>
            <?php 
   $getcats = mysql_query (" SELECT * FROM `categories` ORDER by name ASC");
   while ($showcats = mysql_fetch_array($getcats)) { 
           
            echo "<option value=\"".$showcats['id']."\"".(($_GET['category']==$showcats['id']) ? ' selected="selected"':'').">".$showcats['name']."</option>";
            } ?>
          </select>
    </form>

<form id="make" name="make" method="GET" action="create-advert.php?category='<?php echo $_GET['category']; ?>">
         
          <select name="make" onchange="this.form.submit();">
           <option>--Choose make--</option>
            <?php 
   $getmakes = mysql_query (" SELECT * FROM `makes` ORDER by name ASC");
   while ($showmakes = mysql_fetch_array($getmakes)) {
           
          echo "<option value=\"".$showmakes['id']."\"".(($_SESSION['make']==$showmakes['id']) ? ' selected="selected"':'').">".$showmakes['name']."</option>";
          
   } ?>
          </select>
          </form>


Each time I select the make in the second form the url parameter 'category' disappears from the first?

Many thanks

Hi all

I am building a page to filter SQL values but I'm not sure how to write the code for the query.

My URL looks like this:

stone.php?category=Wood&type=4&colour=1&Submit=Submit

Firstly, can I remove the submit from the URL?

Then I have my code to create the query:

$fetchData=mysql_query("SELECT * FROM `products` WHERE category = "'.$_GET'category.'"");

Can I combine this for the type and colour?

Many thanks
Pete

What this parameter 'absolute' in DateTime::diff does? I have done some tests but i cant percept what is different when i set this parameter 'true'.

Can you explain to me?!

Thanks a lot.

Best regards.

May I know what does this mean, this is the code which they are referring to. I have tried troubleshooting, still could not find the cause, appreciate if anyone can help? Thanks

Hello all,

I'm an absolute Newbie to PHP.  I'm struggling with a problem that I think is extremely basic to you experts but I just can't get it to work.

In short, I have an application that has a link that goes to:

Site1/dir/admin?id=(text)&page=(number)

I want to redirect to a link that's identical except it's Site2 at the beginning instead of Site 1.

What I've attempted so far is this:

<?php

 $GLOBALS[$passid]=$_GET['id'];
 $GLOBALS[$passpage]=$_GET['page'];
 
  header( 'Location: http://site2.com/dir/admin/?page=$passpage&id=$passid');
?>

But it just redirects to
http://site2.com/dir/admin/?page=$passpage&id=$passid
(with all of that text being literally what is in the URL, not the variable values)

I have a feeling I'm doing something small but very basic wrong.

The $GLOBALS thing was an afterthought.  Outcome is the same with or without that.

Any help much appreciated!!!

Hi all,

I have received this error, and I could clearly recall I did not actually change any content in the file.

May I know how should I debug it? Thanks

Hi all

I am in the process of creating a product page where the user can type in three initials into a form and then 'clicks add to basket'.

The button doesn't use a form just a url:

basket.php?action=add&id=1&qty=1

This adds the item into a basket using sessions rather than a database. The question is, how do I add three variables into my form so that they are sent via the URL and into the session?

Wil I have to start again with a form?

Here's the code:

<td class="table-font-grey">Why not make your whip extra special by adding up to three elegantly engraved Kunstler script initials.</td>
            <td width="42" style="border: 1px solid grey;"><input name="initial_1" type="text" size="8" maxlength="1" height="40px" /></td>
            <td width="43" style="border: 1px solid grey;"><input name="initial_2" type="text" size="8" maxlength="1" height="40px" /></td>
            <td width="43" style="border: 1px solid grey;"><input name="initial_3" type="text" size="8" maxlength="1" height="40px" /></td>
          </tr>
          <tr>
            <td height="15">&nbsp;</td>
            <td width="328" class="table-font">&nbsp;</td>
            <td width="42" align="center" class="table-font">1</td>
            <td width="43" align="center" class="table-font">2</td>
            <td align="center" class="table-font">3</td>
            </tr>
          <tr>
            <td>&nbsp;</td>
            <td colspan="3" class="table-font">&nbsp;</td>
            <td align="right" class="table-font">&nbsp;</td>
          </tr>
        </table>
        <hr />
        <p>&nbsp;</p>
        <table width="494" border="0">
          <tr class="table-font">
            <td width="263" height="24">
           
            <a href="<?php echo "basket.php?action=add&amp;id=1&amp;qty=1" ?>" title="Add <?php echo $product['name'] ?> to Cart">
            <a href="<?php echo WEB_URL."basket.php?action=add&amp;id=1&amp;qty=1" ?>" title="Add <?php echo $product['name'] ?> to Cart">
            <img src="<?php echo WEB_URL."images/product-add-button.gif" ?>" alt="Buy <?php echo $product['name'] ?>" /></a>
           
Many thanks

Hi all

I am working on a filter system that when a user selects a drop down menu item it automatically updates the page taking the value from the form and sending it through the URL parameter to update the page accordingly:

<form id="category_filter" name="category_filter" method="post" action="">
        <label for="category_filter"></label>
        <select name="category_filter" id="category_filter" style="width: 160px" onchange="this.form.submit();" >
         <option value="" selected class="meter-calc-text">Category</option>
          <?php

                  $fetchcategories=mysql_query("SELECT * FROM `categories` ORDER BY position ASC");

                  while($returnedcategories=mysql_fetch_array($fetchcategories)) {

                     echo "<option value=\"".$returnedcategories['name']."\" >".$returnedcategories['name']."</option>";

                  }

                  ?>
        </select>
      </form>

The only thing is, it doesn't pass the value to the url, it remains blank

Many thanks for your help.

Pete
