Changed it to <x href and firebug says

syntax error

When it is an 'a' the code outputted by the page is:

<a false="" return="" ).show();="" email_2008-10-09-ab-49_10_1.png="" 1="" pdata="" 10="" 2008-10-09-ab-49="" nmr="" ab="" data="" oct="" 2008="" bruk400data="" .="" ,="" src="" ).attr(="" img#spectra="" onclick="(" href="./nmr/bruk400data/2008/Oct/data/AB/nmr/2008-10-09-AB-49/10/pdata/1/email_2008-10-09-AB-49_10_1.png">F #2</a>
<br/>
<img id="spectra" style="display: none;" alt="" src=""/>

I see that somehow there is a cheeky extra RHS bracket there:

<a false="" return="" ).show();=""

The code I on the page is:

<a href='./nmr/{$row['machine']}/{$row['year']}/{$row['month']}/data/AB/nmr/{$row['servercode']}/{$row['nmrn1']}/pdata/1/email_{$row['servercode']}_{$row['nmrn1']}_1.png' onclick='$j('img#spectra').attr('src','./nmr/{$row['machine']}/{$row['year']}/{$row['month']}/data/AB/nmr/{$row['servercode']}/{$row['nmrn1']}/pdata/1/email_{$row['servercode']}_{$row['nmrn1']}_1.png').show(); return false'>{$row['nmre1']} #2</a>
<br />
<img id='spectra' src='' alt='' style='display:none;'/>

I should really start using your $prefix idea because the long directory structures are doing my head in now.

Eh? I didn't mean <x href=""... - I meant <a xhref=""...

Anyway, no matter - the problem is that you've got single quotes for the HTML attributes, which is conflicting with the JavaScript single quotes, and causing all that funniness to occur.

Use double quotes for the onclick and it should be fine - but that means escaping them with a backslash so PHP echo doesn't get all confused:

onclick=\"...\"

Once you've got that all working, you can replace the URL within onclick section with this.href so you don't have to repeat yourself but also keep your code accessible.

Done, no worky :((

It now, as you would image imagine, looks like this with the backslashes, two needed I assume?

<a href='$prefix{$row['nmrn1']}/pdata/1/email_{$row['servercode']}_{$row['nmrn1']}_1.png' onclick=\"$j('img#spectra').attr('src','$prefix{$row['nmrn1']}/pdata/1/email_{$row['servercode']}_{$row['nmrn1']}_1.png').show(); return false\">{$row['nmre1']} #2</a>
<br />
<img id='spectra' src='' alt='' style='display:none;'/>
 
</span




Still opens the image directly and not within the page.

Ah, bloody PHP - you also need to escape the $ of $j with \

So, your first line now becomes:

<a href='$prefix{$row['nmrn1']}/pdata/1/email_{$row['servercode']}_{$row['nmrn1']}_1.png' onclick=\"\$j('img#spectra').attr('src', this.href ).show(); return false\">{$row['nmre1']} #2</a>


(That also has the second url replaced with this.href)



Once you've done that it'll work.

Yay, thank you for your persistence Peter!

Right. It is all working very nicely now. I had missed the option in IrfanView for PDF to PNG batch conversions so that's all good except for the image quality being a bit poor, but nevermind.

I have a question tho. I want to pull, for example, 5 consecutive rows from my database. Sounds simple enough to me, but I can't get it working how I want.

Current code is...

$tableid = $_GET['id'];
$query  = "SELECT * FROM nmr LIMIT 5 OFFSET $tableid";
 

If id=5 then it gives me entry 5-9, as you would expect. Problem being, the first id in my database isn't 1 due to deleting a few, and if I was to delete entries at a later date even if the first one was 1 it would mess things up. So clearly this code is wrong and I realise this.

I can already get id from the address bar but I then want it to pull the record that has that id and the next 4 records. So the limit is 5 including the record with the id in the address bar.

I've searched and searched but had no luck :(

select * from nmr where id >= offset limit 5

 

edit: oh and you prob want a "order by id asc" just to make sure.

$tableid = $_GET['id'];
$query  = "SELECT * FROM nmr WHERE id >= $tableid LIMIT 5";
 

Of course change the name of the id column, if it's different.

Also, if you're not already you should really be using mysql_escape_string / mysql_real_escape_string on the variables you take from $_GET / $_POST / $_COOKIE etc. to use in your queries, or you risk SQL injection.

I could for instance do:

http://www.yourdomain.com/script.php?id=;DELETE%20*%20FROM%20nmr

And empty your database for you.

Thank you both of you.

Hmm, I think I should too because someone emptying my database would make me cry.

Would this be sufficient?

 
$getid = $_GET['id'];
$tableid = mysql_escape_string($getid);
$query  = "SELECT * FROM nmr WHERE id >= $tableid LIMIT 5";
 

Why use two steps?

Simpler to just do this:

$tableid = mysql_escape_string($_GET['id']);

?

That will work fine.

Personally, if I'm expecting $_GET['id'] to be a number I would use PHP's is_numeric function to make sure that's what it is. If I'm expecting a string or an unknown data type then I'd use mysql_real_escape_string.

if (isset($_GET['id']) && is_numeric($_GET['id'])) {
 
    // No need to escape via mysql_escape_string as we
    // know it's numeric from the is_numeric test in the
    // if statement.
    $table_id = $_GET['id'];
 
    // sprintf can also be used to sanitise input from a user,
    // but it can make code harder to read. In this example %d
    // requires the variable to be an integer. The other types
    // are listed on the manual page.
    $query  = sprintf("SELECT * FROM nmr WHERE id >= %d LIMIT 5", $table_id);
 
    // Rest of your code goes here
 
}else {
 
    // ID is not set in the URL query or it is not a number, show an error here?
 
}

If you want to write better PHP code, turn display_errors on and set error_reporting to E_ALL (both in php.ini) and you can see what PHP really thinks of your script.

I'm still in bed so can't quite comprehend the issue, but do you just need to order them now? The query isn't interested in the missing numbers.

Problem number something:

 

I have a load of the data I want in my database in the form of an Excel spreadsheet. I've now saved it as a CSV and removed all the lines already present. I thought I could import this using PHPMyAdmin but it turns out I can't. I've read that it's possible (from the PHPMA wiki of all places) but for me it only gives me the option to import SQL based files.

 

I've upgraded PHPMA versions from 2.11.6 to 3.1.0 with no luck.

 

How and where does one enable CSV imports/uploads?

Browse into the actual table you want before selecting import, then you get the CSV option appearing.

Sure I tried it that way but I'll check when I get home.

You have to actually browse the table - not simply view it.

It is more convoluted than it needs to be - should have the CSV option available at all levels, and just allow you to select a database/table from a list if it's not obvious where you're importing to.

Thank you!

 

All imported now. All the help from all round has been appreciated. No doubt I'll be back for more.

 

Actually, why am I only able to access PHPMyAdmin on the server itself and not on any locally networked PC?

Don't worry. Found it.

So infinitely much better than PHPMyAdmin. By fuck I hate PHPMyAdmin.

 

(have to allow remote connections from wherever you intend to use the app, obviously)
