Bitte helfen Sie mir über das Problem im Titel angegeben.Warum dieser Hinweis (12-mal): Nicht initialisiert String-Offset: 0 in app_vsf.php on line 90
Der Codeabschnitt ist:
<?php
// framework related things in this file.
// vsf = Very Simple Framework
$vsf = new stdClass;
// default app_layout file
$vsf->app_layout = 'app_layout.php';
// define the 'index' file, where we should link back to.
// Need to include the path, otherwise S.E. friendly URLS get messed up.
$vsf->self = '/mapcal/index.php';
// to support search engine friendly URLS, grab data from PATH_INFO
if (isset($_SERVER["PATH_INFO"])) {
$tmp_array = explode("/",$_SERVER["PATH_INFO"]);
for ($index = 0; $index < count($tmp_array); $index++) {
// only want the odd elements, they are the parameters. The even ones are the values
if ($index % 2 == 0) { continue; }
$_REQUEST[$tmp_array[$index]] = $tmp_array[$index+1];
}
}
// these functions are for form error handling
$errorfields = array();
$errormsgs = array();
$errorwasthrown = FALSE;
function adderrmsg($field = '', $msg = '') {
global $errorfields;
global $errormsgs;
global $errorwasthrown;
if ($field) {
$errorfields[] = $field;
}
if ($msg) {
$errormsgs[] = $msg;
}
$errorwasthrown = TRUE;
}
function displayformerrors($errhdr = 'The following errors occured:') {
global $errorfields;
global $errormsgs;
if (empty($errorfields) and empty($errormsgs)) {return;}
if (! empty($errormsgs)) {
print "<p style='color: red;'>$errhdr<br>\n";
foreach ($errormsgs as $msg) {
print "• $msg<br>\n";
}
print "</p>\n\n";
}
}
function displayformlabel ($field = '', $label = '') {
global $errorfields;
if (in_array($field,$errorfields)) {
print "<span style='color: red;'>$label</span>";
}
else {
print $label;
}
}
function reuseform($formaction = 'new',$field_list = '',$query = '') {
if ($formaction == "new") {
foreach (split(",",$field_list) as $field) {
global ${$field};
${$field} = '';
}
}
elseif ($formaction == 'form') {
foreach (split(",",$field_list) as $field) {
global ${$field};
${$field} = $_REQUEST[$field];
}
}
elseif ($formaction == 'query') {
foreach (split(",",$field_list) as $field) {
global ${$field};
${$field} = $query[$field];
}
}
} // close function reuseform
?>
Die Linie nicht 90 ist: $ {$ field} = $ query [$ Bereich];
Die Bekanntmachung wird 12 mal gezeigt, wie es 12 Felder in der Form sind, aber warum dies zeigt, und ich kann nicht die Daten in Formularfelder für die Bearbeitung Zweck sehen. Bitte helfen Sie mir in Bezug auf dieses Problem.
Ich habe noch nie Gebrauch von '$ {$ var_name}' je in meinem kurzen Programmier Leben gesehen. – hjpotter92

Scheint so, als ob wir vermissen, wo wiederverwendungsform aufgerufen wird. –
