$_GET problem in a function

[Herod]

Hello.

I have a function that need to read from the database and display infos on a page:

here's the code i'll explain down what i was thinking:

 

this is the function:

 

<?php
function text_areas_populated($pag)
{
  $gs = strtoupper(substr($pag, 0,1)); 
  // get the table first letter. all the fields in the database have an letter to define what table they are in
  //sTitlu_roN, sStire_roN for example.

  echo "Title news Romana<br />";
  echo 	'<input class="titlu" type="text" name="titlu_ro" value="'.$row_get_.$pag['sTitlu_ro'.$gs].'" /><br />';
  /*
  ....
  */
  echo "News Romana<br />";
  echo 	'<textarea name="stire_ro" class="stire">'.$row_get_.$pag['sStire_ro'.$gs].'</textarea><br />';
  /*
  ....
  */
}?>

 

and this is the calling of the function:

 

<?php
$sql_get_news = "SELECT * FROM t_news WHERE nIdN = '".$_GET['id']."'";
$res_get_news = mysql_query($sql_get_news) or die (mysql_error(__LINE__));
$row_get_news = mysql_fetch_array($res_get_news);

echo text_areas_populated ($_GET['pag']); // where page in this case is news

 

My problem is that nothing is displayed in the input fields.

Can anyone help me with this problem?

Thank you!

Where do you define this variable?

$row_get_.$pag

 

If it is outside of the function, you probably have a scope issue. Show more code that shows where that variable is defined, and it will be easier to help you.

this is the page:

 

<script type="text/javascript">
function do_change()
{
	if(document.getElementById('id_poza').value == 0)
	{
		document.getElementById('poza_default').innerHTML='<img src="../imag/select_image.gif" />';
	}
	else
	{
		document.getElementById('poza_default').innerHTML='<img src="../imag/poze_stiri/'+(document.getElementById('id_poza').value)+'" />';
	}
}
</script>
<table width="780px" align="center">
<tr>
	<td class="text_top">

                       <?
			echo $_SESSION['news_err']['title'];
			echo $_SESSION['news_err']['stire'];
			echo $_SESSION['news_err']['match'];
		?>
	</td>
</tr>
<tr>
	<td align="center">
		<h3 style="color:#ffffff; font-family:Arial, sans-serif">
      	REVIEW AND PUBLISH NEWS

	</td>
</tr>
<tr>
	<td class="text_top" align="center">
	<form action="stiri_publica.do.php" method="post">

<?php
	$sql_get_news = "SELECT * FROM t_news WHERE nIdN = '".$_GET['id']."'";
	$res_get_news = mysql_query($sql_get_news) or die (mysql_error());
	$row_get_news = mysql_fetch_array($res_get_news);

	echo text_areas_populated($_GET['pag']);


	$sql_select_poze = "SELECT * FROM t_poze ORDER BY sNume_PozaP ASC";
	$res_select_poze = mysql_query($sql_select_poze) or die (mysql_error());
?>

		Select a picture:<br />
		<select id="id_poza" name="id_poza" onchange="do_change()">
			<option value="0">Select a picture</option>
			<?php
			while ($row_select_poze = mysql_fetch_array($res_select_poze))
			{
				?>
				<option value=<?=$row_select_poze['sNume_PozaP']; ?> ><?=$row_select_poze['sAlt_PozaP']; ?></option>
				<?php
			}
			?>
		</select>
		<div id="poza_default"><img src="../imag/select_image.gif"></div><br />
		<div align="center">
			News you are posting will not be automaticaly be inserted into the website. They will be verified by an website admin
			and after that they will be aproved or not to be published!<br /><br /><br />
		</div>
		<input type="submit" class="submit" value="Post news" /><br />
	</form>
	</td>
</tr>
</table>
<?
unset ($_SESSION['news_err'], $_SESSION['posturi_news'], $_SESSION['posturi']);
?>

 

 

and function remain the same.

Please use

tags around you code snippets. Doing so will make them much more readable. Reading RED code is very hard on  the eyes.

Also the function is written in a separate file functions.php
