I'm getting mad with this....

[heohni]

Hi,

after hours and hours...I can't find a solution for the following problem:

In the admin area - I try - before I add a link, I added a new page called link_add_pre_check.php

<?php

include("../application.php");

session_start();

if(isset($COOKIE_USERNAME)) 
  $_SESSION['indexu_session_username'] = $COOKIE_USERNAME;

$_SESSION['indexu_session_location'] = "Administrator Area";
$_SESSION['indexu_session_ip'] = $_SERVER["REMOTE_ADDR"];    

function pre_check_link(){
    global $admin_template_path;
    DisplayTemplate($admin_template_path."link_add_pre_check_form.html","\$novar");
}

DisplayTemplate($admin_template_path."header.html","\$novar");
pre_check_link();
DisplayTemplate($admin_template_path."footer.html","\$novar");

?>

The link_add_pre_check_form.html look like:

<form action="link_add.php" method="post">
<table cellpadding='4' cellspacing='0' border='0' width='50%'>
    <tr>
        <td class=tbl_caption colspan=2>
            Add New Link Step 1
        </td>
    </tr>
    <tr class=tbl_light2>
        <td>Url</td>
        <td width=280><input type=text size=40 name=url value='http://'></td>
    </tr>
    <tr>
        <td class=tbl_dark colspan=2 align=center>
            <input type=submit value="Get Meta Data for this Link" class=button>
            <input type=reset value="Reset" class=button>
        </td>
      </tr>
</table>
</form> 

In the link_add.php I just added a few lines to the function ShowFormAddLink ()

$meta = get_meta_tags($_POST["url"]);
$url             =     $_POST["url"];
$description     =      $meta["description"];
$keywords         =      $meta["keywords"];

  DisplayTemplate($admin_template_path."link_add_form.html", "\$category,\$custom_field_form,\$add_cat1,\$add_cat2,\$url,\$description,\$keywords"); 

In the link_add_form.html I modified:

<tr class=tbl_light2>
        <td>Url</td>
        <td width=280><input type="text" name="url" value="<%url%>" size="50"></td>
      </tr>
...

<td width=280>
        <textarea name=description cols=40 rows=7><%description%></textarea>
        </td>

...

<td width=280>
            <textarea cols="40" rows="7" name="keywords"><%keywords%></textarea>
        </td> 

And I really can't understand why JUST <%url%> is displayed but not the description and the keywords.

Hope someone can understand what I'm trying to to... and can explain how i get the last to vars parsed from the temaplte engine. What I'm doing wrong here???

[heohni]

btw: when I echo those vars

echo $url             =     $_POST["url"];
echo $description     =      $meta["description"];
echo $keywords         =      $meta["keywords"]; 

I get the correct data...it is there - how to get them parsed now?

Hello heohni,

very cool hack! I didn't know that it's that easy to grap meta data with php. I tried your script.

Just get your variables global by

  // vars template
  global $category, $url, $description, $keywords, $custom_field_form, $add_cat1, $add_cat2;

That's it!

I'll use this hack too. You should als include a db check whether the link is already in or not. I might work on that too!

You should make $meta as global var.

global $meta;

why $_POST["url"] no need to be global. Because $_POST, $_GET, $_COOKIE, and other $_ is a 'super global' var.
You do not need to make it global. Be careful when you're inside a function

[heohni]

Cool! I'm so blind... thanks 1000 times and appologize my stupidness :-)

tjoerg, I want to do the same, to check if links are already in the db. But for now just for the admin area, because before i run my engine I need some links there - and they must be entered by hand....and this hack (I didn't know that THIS is a hack ;-)) helps me a lot with it!

[bgray]

This looks awesome but I don't really know how to go about it with the changes. Could someone post a step by step as I'm sure I'd screw it up if I tried from the info here?

It would be much appreciated!

[esm]

actually, all the steps are there. just do one thing at a time. if you have a problem, just post a msg here...

and take a look at tjoerg's signature block...!

[bgray]

esm,

I know it is clear for you but It's not everyone has the same coding background and I think you might be making some assumptions.

I really think this should be in the mod/hack archive.

I can follow the first post just fine but I have no idea where the

//vars template code goes that tjoerg mentions that seems to make this work.

[dody]

Yeah ... I'd love too. Please post a complete hack.

you give me way too much credit. I follow one simple rule: I make mine look like yours ( dody's in this case ). it is simply a case of "monkey see, monkey do" and I am the monkey.

When I coined that phrase "applying a hack takes a knack" which tjoerg uses in his signature block, that is what I had in mind. I'll tell you how I did most of my hacks. Let's say I want to print something on an html page. I found a <%variable%> in that html page and I traced it back to a $variable ( a $ with the same name ) in the applicable php page. I found it usually in the DisplayTemplate function. From there I did a search "up" the page taking note of where the $variable appreared. Then I reversed the process putting my variable in the same place as $variable until I got to the html page where I put my variable inside of <% %>. Monkey, see monkey do. I literally copied what someone else had already done, I just changed the names as I went.

Yep, I have learned a few things. An you will learn them to by doing them. I try to give detailed steps but even then the user has to ocassionally adjust what I have done because their code may be different.

as for things being clear, well, not always. Sometimes ( many times ), I have no clue as to what I am doing. But I see what dody has done ( or maybe someone else ) and I just do what he did. I make mine look like his. A simle rule that works.

The only programming class I have ever taken was in 1967 and we used graph paper ( well, it looked like that except the blocks were big enough to write in ) which were submitted and keypunched into cards. I wrote two "programs" - One to print "Hello World" and one to add two numbers together.

So give it your best shot. and I'll help. ( but it may be a case of the "blind leading the blind" . Or maybe "In the land of the blind, the one-eyed man is King!" )

Sometimes, I just rename the file on the server just in case I mess up badly.
