Parse error: syntax error, unexpected '->' (T_OBJECT_OPERATOR)

php syntax-error

Solution 1

if (!this->setDate

This line is missing a $ before this, so this is being treated as a constant, which doesn't exist so is treated as a string, which can't have -> after it.

Solution 2

You are missing a $ sign:

if (!this->setDate_array($GLOBALS['$this->name'])) {

should be

if (!$this->setDate_array($GLOBALS['$this->name'])) {

I have a feeling this may be a simple syntax error that I'm just not seeing, as I've had a poke around the code and cannot figure out why I'm getting the above error. The code I'm working on is a tutorial from a SAMS books, on building a calendar class. For the record, I'm running PHP 5.4.7. The below code belongs to an include that I'll show below..

function date_pulldown($name) {
    $this->name = $name;
}

function setDate_global( ) {
    if (!this->setDate_array($GLOBALS['$this->name'])) {
        return $this->setDate_timestamp(time());
    }

    return true;
}

function setDate_timestamp($time) {
    $this->timestamp = $time;
    return true;
}

function setDate_array($inputdate) {
    if (is_array($inputdate) &&
        isset($inputdate["mon"]) &&
        isset($inputdate["mday"]) &&
        isset($inputdate["year"])) {

        $this->timestamp = mktime(11, 59, 59, $inputdate["mon"], $inputdate["mday"], $inputdate["year"]);

        return true;
    }

    return false;       
}

function setYearStart($year) {
    $this->yearstart = $year;
}

function setYearEnd($year) {
    $this->yearend = $year;
}

function getYearStart() {
    if ($this->yearstart < 0) {
        $nowarray = getdate(time());
        $this->yearstart = $nowarray[year]-5;
    }

    return $this->yearstart;
}

function getYearEnd() {
    if ($this->yearend < 0) {
        $nowarray = getdate(time());
        $this->yearend = $nowarray[year]+5;
    }
    return $this->yearend;
}

function output() {
    if ($this->timestamp < 0) {
        $this->$setDate_global();
    }
    $datearray = getdate($this->timestamp);
    $out = $this->day_select($this->name, $datearray);
    $out .= $this->month_select($this->name, $datearray);
    $out .= $this->year_select($this->name, $datearray);
    return $out;
}

function day_select($fieldname, $datearray) {
    $out = "<select name=\"$fieldname"."[mday]\">\n";
    for ($x=1; $x<=31; $x++) {
        $out .="<option value=\"$x\"".($datearray["mday"]==($x)?" SELECTED":"").">".sprintf("%02d", $x)."\n";
    }
    $out .="</select>\n";
    return $out;
}

function month_select($fieldname, $datearray) {
    $out = "<select name=\"$fieldname"."[mon]\">\n";
    for ($x=1; $x<=12; $x++) {
        $out .="<option value=\"".($x)."\"".($datearray["mon"]==($x)?" SELECTED":"")."> ".$this->months[$x-1]."\n";
    }
    $out .="</select>\n";
    return $out;
}

function year_select($fieldname, $datearray) {
    $out = "<select name=\"$fieldname"."[year]\">";
    $start = $this->getYearStart();
    $end = $this->getYearEnd();
    for ($x=$start; $x<$end; $x++) {
        $out .="<option value=\"$x\"".($datearray["year"]==($x)?" SELECTED":"".">$x\n";
    }
    $out .="</select>\n";
    return $out;
}
}
?>

Does the error give a line #?

What is the exact and complete error message? Which line of code does it correspond to?
Keeleon about 11 years

Btw after you fix that you have an error in year_select(). $out .="<option value=\"$x\"".($datearray["year"]==($x)?" SELECTED":"".">$x\n"; should have a closing parens after the :""

@JohnConde - sorry about that, the initial error was on line 14.
