PHP：查询函数erron执行更新查询字符串

Question

我遇到查询问题。这个查询适用于phpMyAdmin，但是当这个查询由PHP执行时我有一个错误。可能是什么原因？

我的PHP代码：

var_dump($sql); 
query($sql); 

当我调试：

这是查询字符串：

UPDATE searchcolumnsets SET name = "Project X",jsonfields = "[{\"name\":\"cm:contentPropertyName\",\"title\":\"Thumbnailed Content Property Name\",\"description\":\"\",\"datatype\":\"\"},{\"name\":\"cm:defaultHomeFolderPath\",\"title\":\"Percorso cartella homepage\",\"description\":\"\",\"datatype\":\"\"},{\"name\":\"trx:enabled\",\"title\":\"Abilitato\",\"description\":\"\",\"datatype\":\"\"},{\"name\":\"cm:identifier\",\"title\":\"Identificativo\",\"description\":\"\",\"datatype\":\"\"},{\"name\":\"cm:expiryDate\",\"title\":\"Data di scadenza\",\"description\":\"Data di scadenza\",\"datatype\":\"d:date\"},{\"name\":\"cm:hits\",\"title\":\"Conteggio\",\"description\":\"Conteggio\",\"datatype\":\"d:int\"}]" WHERE id = 50 

这是错误：

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'name":"cm:contentPropertyName","title":"Thumbnailed Content Property Name","desc' at line 1

Answer 1

你可能会使用单一的qoute。 试试这个

UPDATE searchcolumnsets SET name = 'Project X',jsonfields = '[{\"name\":\"cm:contentPropertyName\",\"title\":\"Thumbnailed Content Property Name\",\"description\":\"\",\"datatype\":\"\"},{\"name\":\"cm:defaultHomeFolderPath\",\"title\":\"Percorso cartella homepage\",\"description\":\"\",\"datatype\":\"\"},{\"name\":\"trx:enabled\",\"title\":\"Abilitato\",\"description\":\"\",\"datatype\":\"\"},{\"name\":\"cm:identifier\",\"title\":\"Identificativo\",\"description\":\"\",\"datatype\":\"\"},{\"name\":\"cm:expiryDate\",\"title\":\"Data di scadenza\",\"description\":\"Data di scadenza\",\"datatype\":\"d:date\"},{\"name\":\"cm:hits\",\"title\":\"Conteggio\",\"description\":\"Conteggio\",\"datatype\":\"d:int\"}]' WHERE id = 50
