[Resolved] Emptying a Table

uniflare

Hm, ok, i was wonderin how to get a table, eg:

<table><tr><td>BLAHBLAH</td></tr></table>

and empty it so it becomes:

and then add some stuff like this:

<table><tr><td>Hello</td></tr></table>

Any ideas? Maybe if i get what is between the <td></td> tags and then replace it with something like "#~#" and then Explode it into two arrays... or just replace it with what i want in there, any ideas guys/gals?

Well are you trying to make a template?
What exactly are you trying to do here.

uniflare

Well its sorta a new idea.. a bit complicated, i want to make a template creation tool based on another template... so id like grab examle tables from another template and use them in the new one, could also be use for fixing templates and errors in html design, so it can dynamically create a template based on the first template the user gives. So yeah, make a template with given table data, (with data inside)

planetsim

Try something like this

<table><tr><td>{replacement}</td></tr></table>

Then with PHP

$string = str_replace("{replacement}","Hi this is PHP",$string);

uniflare

LOL i can do a lot more tricks than that with templates.... thats not what i mean, i mean i want to get what is BETWEEN <td> and </td> and then REPLACE it...

so if i had:

<table>
<tr>
<td>
Some text i want to replace
</td>
</tr>
</table>

Then i would want to replace whatever is between <td></td> with something else of what i choose... in this case i want to replace "Some text i want to replace", so im MAKING a template...

Maybe a preg_match, and str_replace...

So i want to know what is between <td> and </td>

planetsim

Ok now i see what you wanna do.

What your trying to do is impossible to a certain extent. If you decided to have more <td></td>'s you couldnt do it.

Im not sure on how you do it exactly. But its gonna take more than just preg_match

You'll need to use the file system functions
eg.

fopen
fgets
fputs
etc

I could most likely do it if it were 1 td, with substr() strpos() ereg_replace()... but i wanted to see if i could do it with more than 1 td 🙁... If someone out there knows, (and someone does), then PLEASE tell me... im pretty sure you use an ereg_replace() to replace anything between <td></td>, and thats it... im sure i heard it somewhere.... 🙁

I have found out how to replace whats in every table....

But i want it a little better, like Just a common table, one thats used often in the page.. Could anyone try beef up this script i made for me?

$str = "<table width='100%'><tr><td width='50%'>HELLO</td><td width='50%'>HELLO</td></tr></table><br>
<table width='100%'><tr><td width='100%'>HELLO</td></tr></table><br>
<table width='100%'><tr><td width='100%'>HELLO</td></tr></table><br>";

echo("<b>BEFORE: </b><br>".$str."<br><BR>");

$str = @ereg_replace("<td([^>]+)>","\\0{td}",$str);

$str = @ereg_replace("<([^>]+)td>","{td}\\0",$str);

$str_arr = explode("{td}",$str);

$i = "1"; $c = count($str_arr);

foreach($str_arr as $item)
{
	if($i % 2 == 0)
	{
		$l = $i - "1";
		$str = str_replace($str_arr[$l],"",$str);
	}
	$i++;
}

$str = @str_replace("{td}{td}","YO NEW CONTENT",$str);

echo("<b>AFTER: </b><br>".$str);

Any help Greatly Appreciated, And thanks for helping so far 😉

PS: I only used:

ereg_replace();
str_replace();
explode();
foreach();
count();

and only used echo() to test it 😛, and i did this in 35 minutes 😃

The script isn't ouputted properly on the forum... in the first 2 ereg_Replace() functions there is "\0", replace this with "\0" to get it to work....

Something like a StrBetweenStr() function might help...

uniflare

Does strbetweenstr() accept Patterns, otherwise there is no way of using it unless i know what the exact code is? and i never will as its on-the-fly lol

superwormy

Your post implies that you're looking to find anything between <td> and </td> tags...

That StrBetweenStr() function will find all occurences of stuff between <td> and </td>, yes... unless I misunderstand you...

Then you could just replace it...

uniflare

What i mean is will it be able to find anything between:

by using a patterns? such as the patterns in the ereg_replace() above?

superwormy

No, but you could just do <td and /td> and that would cover all your bases... just a little tweaking afterwards.

uniflare

Sorry thats not what im looking for... i need to keep the <td></td> tags completely the same... anyway, i just want to know how i can get an array of every single table on the page... eg an array that looks like:


Array (

   [0] => "<table><tr><td></td></tr></table>",

   [1] => "<table><tr><td></td></tr></table>",

   [2] => "<table><tr><td></td></tr></table>"

);

etc... something like that... so i can compare them and see which is most common...

superwormy

Can you post a link to an example of a page which you'd lik eto pull that array from...?

uniflare

Nevermind, Thanks for helping... i figured it out myself 😃... Ill mark this thread Resolved 😃

superwormy

How bout sharing the solution with the rest of us...?

uniflare

Ok but i know how to do it... but havn't written the code yet... lol, ill write the code in a sec and doc it

uniflare

This code only works with signled tables, that means it wont work if a table is INSIDE another table, eg:

well, heres the code:

<?php


# :::: THE HTML PAGE
	$str = "<table width='100%'><tr><td width='50%'>HELLO</td><td width='50%'>HELLO</td></tr></table><br>
	<table width='100%'><tr><td width='100%'>HELLO</td></tr></table><br>
	<table width='100%'><tr><td width='100%'>HELLO</td></tr></table><br>
	<table width='100%'><tr><td width='100%'>HELLO</td></tr></table><br>";

# :::: SURROUND TEXT INSIDE THE <td></td> TAGS
	$str = @ereg_replace("<td([^>]+)>","\\0{td}",$str);
	$str = @ereg_replace("<([^>]+)td>","{td}\\0",$str);

# :::: GET THE <td></td> ARRAY
	$str_arr = explode("{td}",$str);

# :::: REPLACE THE SURROUNDED TEXT
	$i = "1";
	$c = count($str_arr);
	foreach($str_arr as $item)
	{
		if($i % 2 == 0)
		{
			$l = $i - "1";
			$str = str_replace($str_arr[$l],"",$str);
		}
		$i++;
	}

# :::: REPLACE THE REPLACEMENT WITH THE REPLACEMENT lol
	$str = @str_replace("{td}{td}","{content}",$str);

# :::: DO IT ALL OVER AGAIN WITH THE TABLE TAGS ;)
	$str = @ereg_replace("<table([^>]+)>","{td}\\0",$str);
	$str = @ereg_replace("<([^>]+)table>","\\0{td}",$str);
	$str_arr = explode("{td}",$str);
	$i = "1"; $c = count($str_arr);
	foreach($str_arr as $item)
	{
		if($i % 2 == 0)
		{
			$l = $i - "1";
			$str = str_replace($str_arr[$l],"",$str);
			$str_list .= $str_arr[$l]."|-+-|";
		}
		$i++;
	}

$arr = explode("|-+-|",$str_list);
$c = count($arr) - 1;

# :::: GIVE THE INFORMATION
	echo("<b>".$c."</b> - Tables<br><br>");
	for($i=0;$i<$c;$i++)
	{
		$j = $i + "1";
		echo("<b>".$j.":</b><br>".$arr[$i]."<br>");
	}

?>

PS: REMEMBER TO REPLACE "\0" WITH "\0" IN THE SCRIPT AS V-BULLETIN WONT POST THAT CODE PROPERLY
