its a simple code but I'm just learning it so... I can't seem to find what my error is exactly:
"UPDATE `".$table_name_4_updating."`
SET id_capuchon = `".$id_selector_4_updating."`,
referencia_capuchon= `".$referencia_4_updating."`,
medida_capuchon= `".$medida_4_updating."`,
material_capuchon= `".$material_4_updating."`,
calibre_capuchon= `".$calibre_4_updating."`,
impresion_capuchon= `".$impresion_4_updating."`,
presentacion_capuchon= `".$presentacion_4_updating."`
WHERE id_capuchon=`".$id_selector_4_updating."`";
I tried changing the the WHERE
clause to WHERE id_capuchon= '.$id_selector_4_updating.'
and other different ways but all it does is changes from unknown column foobar in field list
You should change the backtick ( `
) characters to single quotes ( '
).
Example:
UPDATE
$table_name_4_updating
SET
id_capuchon = '$id_selector_4_updating',
referencia_capuchon = '$referencia_4_updating',
medida_capuchon = '$medida_4_updating',
material_capuchon = '$material_4_updating',
calibre_capuchon = '$calibre_4_updating',
impresion_capuchon = '$impresion_4_updating',
presentacion_capuchon = '$presentacion_4_updating'
WHERE id_capuchon = '$id_selector_4_updating'
You're using `backticks` around the value in the WHERE clause (and in every assignment too, actually).
This type of quotes is used in SQL to refer to a field name . So here, MySQL is looking for the field named "2" (the value of your variable $id_selector_4_updating
) but this field doesn't exist, hence the error.
You should remove them:
$sql = "UPDATE $table_name_4_updating SET
id_capuchon = '$id_selector_4_updating',
referencia_capuchon = '$referencia_4_updating',
medida_capuchon = '$medida_4_updating',
material_capuchon = '$material_4_updating',
calibre_capuchon = '$calibre_4_updating',
impresion_capuchon = '$impresion_4_updating',
presentacion_capuchon = '$presentacion_4_updating'
WHERE id_capuchon ='$id_selector_4_updating'";
