[Resolved] using [] with variable

revez2002

Hello all,

I am trying to update the values submitted from a dynamically generated form field called $proj_chk_ID[]. Because it is dynamically created, I am using brackets [] and the end of the field name in order to hold the different values. However, when I upload and view the page with this script, I get the following message.

Parse error: parse error, unexpected ']', expecting T_STRING or T_VARIABLE or T_NUM_STRING in /public_html/content/projects/proj001.php on line 1770

Any suggestions?

echo "<select class=\"lite_orange\" name=\"$proj_chk_ID[]\" style=\"height:20px; width:48px;\">";

$checklist_value_query = mysql_query("SELECT proj_chk_value_status 
FROM PROJECT_CHECKLIST_VALUES 
WHERE proj_chk_ID='$proj_chk_ID' AND proj_ref_ID='$proj_ref_ID'");
$checklist_value_row = mysql_fetch_array($checklist_value_query);
$proj_chk_value_status = $checklist_value_row['proj_chk_value_status'];

echo "<option selected value=\"$proj_chk_value_status\">"; echo $proj_chk_value_status;
echo "</option>";				
echo "<option value=\"no\">no</option>";	
echo "<option value=\"yes\">yes</option>";
echo "<option value=\"n/a\">n/a</option>";
echo "</select>";

What line is 1770?

try pulling the $ out of the following line to make
echo "<select class=\"lite_orange\" name=\"$proj_chk_ID[]\" style=\"height:20px; width:48px;\">";
become
echo "<select class=\"lite_orange\" name=\"proj_chk_ID[]\" style=\"height:20px; width:48px;\">";

Even after pulling the $ out, I had no success updating the database. However, I did a Google search, and found some info on variable variables.

echo "<select class=\"lite_orange\" name=\"${$proj_chk_ID}[]\" style=\"height:20px; width:48px;\">";

This eliminated the parse error, but I still can't update my database.

Well, this is another problem (involving a completely different part of your code, for example). Rather than having two questions in one thread, I'll mark this one resolved and you can start a fresh thread with a fresh question.
