is there ay easy way to do this in php?

[shadiadiph]

I know it can be done with anchor tags in html but it looks messy

 

I have some links A-Z clicking 'A' should only display the paragraphs that are started with A like APPLE ANT etc and clicking B BALL BAT etc

 

<td class="two"><a href="<?=???>">A</a></td>
<td class="two"><a href="<?=???>">A</a></td>
<td class="two"><a href="<?=???>">A</a></td>


<p>APPLE</p>
<p>ANT</p>
<p>BAT</p>
<p>BALL</p>

 

 

Does anyone have any idea how to make this work i can'y think of the work around??

It depends on what you mean by "only display".  If you're looking to do that in real time, you'd need to use Javascript.  If you're willing to let a page load happen in between, then use a GET var. 

 

Is there any PHP code outputting the paragraphs?  Where does that paragraph information get pulled from?

[shadiadiph]

wouldn't a page load require javascript too? this why i am asking i am not sure how to do this

When he says "page load" he is referring to when the page reloads after you hit a submit button.

Yes, PHP can reload a page without javascript. And it doesn't have to be with a submit button. It can just be a text link, too.

 

There's several ways to code it. One way is like so:

<form method="GET" action="{$_SERVER['PHP_SELF']}">
<a href="{$_SERVER['PHP_SELF']}?variable=A">A</a>
<a href="{$_SERVER['PHP_SELF']}?variable=B">B</a>
</form>

you can do this in php or javascript

 

php:

 

<?php
  function removeAllOther($var,$key,$let) {
    $letter = $var{0};
    if (strtolower($letter) == strtolower($let)) return true;
    return false;
  }
  $array = array("Apple","Ant","Bat","Ball");
  $ord = $_GET['ord'];
  if (strlen($ord) == 1) {
    // sorry I like to use strlen for variable checks :S sue me
    array_filter($array,"removeAllOther",$ord);
    print_r($array);
  }
?>

^^ for the above make all links look like: http://whatever.com/whatever.php?ord=a or b or c etc

javascript code:

 

<script type="text/javascript">
  var list;
  function sortIt(ord) {
    e = document.getElementById("results");
    if (!list.length) {
      list = e.getElementsByTagName("p");
      for (a in list) {
        list[a] = list[a].innerHTML;
      }
    }
    e.innerHTML = "";
    for (i in list) {
      if (list[i].toUpperCase().substr(0,1) == ord.toUpperCase()) {
        p = document.createElement("p");
        p.appendChild(document.createTextNode(list[i]));
        e.appendChild(p);
      }
    }
  }
</script>
<div id="results">
  <p>Apple</p>
  <p>Ant</p>
  <p>Bat</p>
  <p>Ball</p>
</div>
<a href="javascript:sortIt('A');">A</a>
<a href="javascript:sortIt('B');">b</a>
