[[SOLVED] dynamicly creating multiple page]

well ideally you want to be just taking 20 images from the directory as you need them otherwise you will be downloading every image everytime...

 

Of course you could implement some sort of cache to speed things up...

 

How many images are we talking maximum?

maybe you could get the students to refine it futher as a bit of home work

[Setting variable in java]

what is it you want to set into a variable? the result of that code?

 

Well wrap it inside a function and then assign the function to the variable.

 

public String myFunc()

{

    //code here

}

 

private String myVar = myFunc();

[SimpleXML and PHP performance hit?]

I have a web menu that is now generated from an XML file and I was intending to use the menu.xml file to generate a sitemap whenever needed.

 

My question is will that start to put a lot of load on the server and start to slow my site if the site gets big? Should I just write a script to write the sitemap to file and just run the script when i update the site?

 

Thanks

[[SOLVED] Add to POST from anchor]

thanks, instead of having a hidden form for each link i updated the hidden field before i submitted here it is if anyone else has a similar problem

 

	function submitform(link)
{
	document.getElementById("hiddenMonth").value = link.innerHTML
	form = document.getElementById("newsForm");
	//submit form
	form.submit();
}

 

and the anchor was <a href='#' onclick='submitform(this); return false;'>$month</a>

[MySQL Help (mysql_fetch_array?)]

the variables will be available outside your script like so..

 

require('templates/$theme/index.tpl');

 

what ever the key value was is the name of your variable...

[[SOLVED] Add to POST from anchor]

yes i like that idea, thanks for the suggestion..

[MySQL Help (mysql_fetch_array?)]

thats because you want the value column this $row["site_name"] should be $row['value']

 

you might want to try the code below if you have that many settings to retrieve.

 

im presuming you only have two columns, setting and value this will get the value of setting and make it a variable storing the correct value inside it...

 

$sql = "SELECT * FROM (yourprefix)_config"; 
$result = mysql_query($sql);

while ($row = mysql_fetch_row($result)) 
{

$$row[0] = $row[1];

echo "KEY: " . $row[0] . " - Value: " . $row[1] . "<br />";

}
echo $site_title;

 

 

[[SOLVED] Add to POST from anchor]

Is it possible to add values to the post array from an anchor link?

 

so my anchor is this <a href="news.php">January</a> is their anyway to add January to the post array which will be detected on news.php.

 

I know i can use GET and just add it to the URL or instead of having anchors have a form which POST to news.php with buttons and style them like links, but i don't want to do this because it affects the layout to much..

 

Ben

[MySQL Help (mysql_fetch_array?)]

can we see all your code... that is not a problem with the query if your table structure is how you said..

 

Ben

[MySQL Help (mysql_fetch_array?)]

have you had a go at this already?

 

use this as your query

 

"SELECT value FROM (yourprefix)_config WHERE setting = 'site_title'"

 

This will return only one row containing your site title, have a go and post back what you have.

 

well one row presuming you only have site_title in the setting column once, which you should have

[[SOLVED] Count and multidimensional arrays]

for($i = 0; $i < count($update); $i++)         
{
    for($j=0; $j < count($update[$i]); $j++
    {
          //check here using $update[$i][$j]

    }             
            
         
}   

[Inserting when NULL]

yes you need to change them to allow null as a value.

 

As daniel said for having empty strings you are checking against that already with this code.

 

if(empty($Gender))
   $Gender == null;
else
   $Gender = $_POST["Gender"];   

[Inserting when NULL]

do you have a constraint on you table in mysql that does now allow null as a value? because otherwise that should work...

 

If you check and their are no constraints on the column post your query here...

 

When you say it doesn't work, what errors are you getting?

[Inserting when NULL]

well isset() checks if the variable was ever set.

 

if $_POST["postedvariable"] is empty you can check this also like so

if(empty($_POST["postedvariable"]))
{
    //more code
}

 

if $_POST["postedvariable"] actually contains the value null you will have to check for this seperatly like so

 

if($_POST["postedvariable"] == null)
{
    //more code
}

 

with these examples you should be able to put them together and take action accordingly...

 

Ben

[Inserting when NULL]

try this

 

if(isset($_POST["postedvariable"]))
{
    $variable = $_POST["postedvariable"];
}

[difficult to add page numbers to this pagination ?]

well the only way you can get to the else statement for "No pictures" is if your last page equals 0. $lastpage is only set in once place which is here. 

 

$lastpage = ceil($numrows/$rows_per_page);

 

Now we know $rows_per_page = 1 so $numrows must be set to zero, try echoing out query_data[0] to see if it contains the correct result on each page....
