Remove the backslash before $wheremulti - you want it to be interpolated into the desired logical operator before the eval() expression is executed.@NogDogAug 19.2005 — #
I've done stuff off-and-on with PHP for the last 2-3 years, really started learning it in the last year or less. But I've been in the IT business for over 15 years now and have dabbled in a lot of UNIX shell scripting and a bit of Perl before ever touching PHP. As PHP has a lot of similarities to them, I guess I picked it up relatively easily as compared to coming into it with no such background.
Using a veriable as an operator
Hi,
I am using an if statement but the operator is a variable, but php doesn’t seam to like is and i get this error msg: –
Parse error: syntax error, unexpected T_VARIABLE in xxx on line 616
The code is this: –
[code=php]
//Form: –
<select name=”whereOperator2″>
<option value=”==”>Equal to</option>
<option value=”>”>Greater than</option>
<option value=”<“>Less than</option>
</select>
//Code Line 616
if ($data[$whereColumn] $whereOperator $whereClause)
Any gd ideas to get around it other than creating another if statement of the 3 variables in the select i.e
[code=php]
if ($whereOperator == ‘==’) {
if ($data[$whereColumn] == $whereClause) {
//code
}
} else if ($whereOperator == ‘>’) {
if ($data[$whereColumn] > $whereClause) {
// and so on
Thanks
Adam

exec("$result = ($data[$whereColumn] $whereOperator $whereClause);");
if($result)
{
# comparison returned TRUE
}
else
{
# comparison returned FALSE
}

I am trying to now get it to do this query but i get an error
[code=php]
eval("$eval_result = (($data[$whereColumn] $whereOperator $whereClause) $whereMulti ($data[$whereColumn2] $whereOperator2 $whereClause2));");
//whereMulti is : -
<input type="radio" name="whereMulti" value="&&" checked>And<input type="radio" name="sqlOperation" value="||" >OR
[/code]
Sorry to be a pain :s
The error is : - Parse error: syntax error, unexpected T_VARIABLE in location/file.php(619) : eval()'d code on line 1
