Ignorance question...

Indiv

I've got a page which consists of a form, and php.
Now, I'm trying to make php be ignorant(just an expression, you language-freaks) to the HTML, but to insert it's own content, depending on an if condition... And I don't know how to do it...

Basically, the page's source looks like that:
<?
PHP stuff...
?>

I want the HTML be proccessed anyway, but the php to be responding to the if condition...

How can I do that?

Hi,

THx for making this an clear question, ahum. Perhaps for the next time. .Be a bit more copncrete..

Anyway:

<?php

if(SOMECONDITION)
  {
   $condition_met = true;
  }
else
  {
   $condition_met = "";
  }

?>

whatever you like to do


<?
if($condition_met)
  {
   // do your thing
   }

?>

Indiv

Um...
It doesn't help.

I'll try to make it clearer:
I want the HTML that is between the if's {}'s to be executed anyway, independent on whether the condition was met or not, while the php should be proccessed only if the condition is met.

It means that if my page contains a:
<table>
<?php if (condition met) {
<tr>
<td>
blablabla...
</td>
<?php echo "<td>something</td>"?>
<td>
blablabla.
</td>
<?php } ?>
</tr>
</table>

The two cells containing "blablabla" would be seen in any case, but the middle cell with "something" should be seen only if the condition is met.

I will even explain why:
I've got pieces of php scattered all around the form/table I'm working with, and opening an "if ($condition_met)" for each one of them is a bother... Doing it once is OK, but every time would be internal suffering... Is there something that could help me out here?

Indiv

Please, people, can I get some help on that?
(Sorry for spamming...)

The reason for not getting answers, is that you first say it works, and then change your post to it doesn't work.

As I posted in the first post..

You need to be clearer in what the problem is, or what you want to do / are doing.

Probably trere is a very simple solution. But if it is not clear what you want to achieve//

Anyway. the solution I gave you in principle works. But if you ahev many cases..

Again.. What are you trying to do / doing!?

Indiv

I don't know how I can be clearer.

I've got a form.
In case some condition is true, the value of many different <input> tags is changed by php. The form itself should appear independent of php, but whether the wanted values are present needs to be determined by the condition.

It means that if the page is:

<?php if ($some_condition) { ?>
<form>
  <input type="text" name="one" value="<?php echo $variable1 ?>"/>
  <input type="submit"/>
</form>

<?php } ?>

And $some_condition=false the form with the text field and the submit button should appear, but the value of text field "one" should be "". Waht I get here is a blank page when the $some_condition=false. Is there a solution?

Yeah, I can't really understand what you are getting at either. But I can guess...if $some_condition isnt' enough, you need to do the test first off for true/false/'1'/whatever...

<?php if ($some_condition == TRUE) { ?> OR
<?php if ($some_condition == '1') { ?> OR
<?php if ($some_condition == $the_test) { ?> 

<form>
  <input type="text" name="one" value="<?php echo $variable1 ?>"/>
  <input type="submit"/>
</form>

<?php } else { ?>

  // it's false or 'the other'...

<?php } ?>

ORRRRRRRRRRRRRRR...without the else condition...I can't tell what you really want...

<?php if ($some_condition == TRUE) { ?> OR
<?php if ($some_condition == '1') { ?> OR
<?php if ($some_condition == $the_test) { ?> 

<form>
  <input type="text" name="one" value="<?php echo $variable1 ?>"/>
  <input type="submit"/>
</form>

<?php } ?>

Indiv

I think what you've now posted is the "long way".
I can take the form, and make 2 copies:
One would be in the condition that $some_condition is true, and the other wuold be if $some_condition is false.

BUT, I'm looking for a more line-economic way of coding.

leatherback

OK,

How about this then:

Say you have 10 items, then you create an array, items:

$items = array()

// make sure the items are empty

for($i =0; $i<10; $i++)
  {
  $items[$i] = "";
  }

if($condition_met)
  {
   $item[0] = $somevalue;
   // for all, or through a lookm, if database results or something
   }


?>


In the input fields you can now just <? echo $items[0]?> to get the value of the first item, (of course with the 0 as 0, 1, 2, ... )

PS: If this doesn't help, you might be more concrete by, say, posting the condition, the way of getting data, etcetc

You could try learning how to code better, more efficiently. Like by using some functions and/or classes.

Sheesh...

Forums Are for Help - not So You Can Look Like an Idiot.

Those are your words... :bemused:

Anyway...
I'll try the array thing...
Sounds like it'd work...

leatherback

What he meant was:

You could write a small function, e.g., called fill_me($element) which you could easily call in each formelement:

<?fill_me(1)?>

which would safe you a lot of code scattered around. And probably the whole setup could be done more efficiently. But -as already posted in the firstreply- if you post unclear questions, and seem to refuse to give us more to work with, you are going to get sub-optimal solutions.

Anyway/ I have given you 2 alternatives. If it doesn't suit your coding wishes, good luck.

And I most certainly did write them.

Indiv

Thanks people.
It does work now:

I've written two functions - set_class($item), and set_value($item), and made the if in them instead of the beginning of the form, so now it works 100% like I wanted it to.

Thank you again.

P.S.: Oh, and sorry for all the bother... I'll try to be clearer the next time. :bemused:
